Aspiring biomedical researchers and health care professionals gained hands-on research training during three weeks at Sanford Burnham Prebys

On Friday, July 25, 2025, the Sanford Burnham Prebys community celebrated the contributions of six high school student interns from the Preuss School. Located on the University of California San Diego campus in La Jolla, the Preuss School educates students striving to be first-generation college graduates.

Participants in the Preuss internship program gained valuable hands-on research experience over three weeks. This program is generously funded by Peggy and Peter Preuss, and Debby and Wain Fishburn.

The students were split into teams of three to complete complementary experiments while studying the common fruit fly.

“The interns have learned biological concepts and experimental techniques, and also participated in career development workshops,” said Yuk-Lap (Kevin) Yip, PhD, a professor and the interim director of the Center for Data Sciences at Sanford Burnham Prebys, during the July 25 capstone presentation.

“Over the course of just three weeks, they have learned about how an unhealthy diet will affect the health of fruit flies.”

The interns discussed what attracted them to the program and presented the results of their experiments.

“I chose this program because I wanted to learn more about biology and the biomedical research field,” said intern Ahmed Ahmed.

“I want to become a forensic scientist,” said intern Mia Gidey. “I know I need to have hands-on lab experience, so this program was really beneficial for me.” 

“This program has helped me develop a better understanding of what I would like to pursue as a career,” said intern Joshua Hernandez.

In addition to studying the effects of high-fat and high-sugar diets on fruit flies, the participant teams also had the opportunity to learn additional research techniques during workshops.

“We were able to conduct flow cytometry experiments with our mentor, Theo Tzaridis,” said intern Bella Dinh. Flow cytometry is a technology that analyzes single cells or particles as they flow past one or more lasers while suspended in a fluid. The interns used the technique to examine proteins on the surfaces of cancer cells that affect the activity of immune cells and the effectiveness of immunotherapy.

“Our group took part in an STK4 inhibitor screening workshop with our mentor, Josh Minyard,” said intern Daniela Ledesma. The participants learned about the drug discovery and development process and went hands-on to compare the efficiency and potency of three drug candidates.

“Thank you so much to everybody that helped us throughout this journey,” said intern Kenia Avila. “We appreciate all of you and we are so grateful for everything that you’ve done.”

Katya Marchetti, a graduate student at Sanford Burnham Prebys and coordinator of the 2025 Pruess internship program, provided closing remarks following the interns’ capstone presentations.

“I am just completely blown away by how incredible every single one of you are,” said Marchetti. “Beyond the techniques and protocols you learned, I hope that you walk away from this summer with a better idea of what you might want to pursue as a career as well as the ability to think like a scientist.”

Q & A with Postdoctoral Researcher Huijie Huang, PhD from the Huang Lab

AuthorCommunications
Date

August 1, 2025

With a deep curiosity about the brain and a passion for solving complex problems, Huijie Huang is a postdoctoral researcher in the lab of Dr. Timothy Huang at Sanford Burnham Prebys, where she is investigating the molecular underpinnings of Alzheimer’s disease. Her journey began in college with hands-on behavioral pharmacology research and evolved into a focused exploration of depression and neural circuits during her PhD. Now, she is using cutting-edge molecular tools to develop gene-based strategies for treating neurodegenerative disease.

When and how did you become interested in science?
In college, I had the opportunity to join a pharmacology lab. This gave me the chance to test how certain drugs effected the animal behaviors. I found it very interesting that these animal behaviors can mimic some types of human behaviors. I was really excited by this. 

How has your scientific career evolved? 
I was so fascinated with the principles of neural regulation of animal behavior, so I chose to focus my PhD on neuroscience. During my PhD, I did a lot of projects related to depression, where I established mouse models to mimic anhedonia and social defeat. These models enabled me to investigate dysfunctions in brain circuits associated with depressive behaviors. 

After graduating, I felt the need to pursue deeper research into the molecular biological mechanisms underlying behavioral changes. I’m fortunate to be a postdoctoral researcher in Dr. Timothy Huang’s lab, where my project focuses on investigating the molecular mechanisms of sporadic Alzheimer’s disease. The lab’s diverse expertise includes molecular biology, genetics and neurobiology, and has allowed me to approach the project from multiple angles and think more broadly and translationally about the impact of our research. 

What brought you to the Huang lab at Sanford Burnham Prebys? 
I was fascinated by the research projects in Dr. Timothy Huang’s lab. After the interview, I realized I would have the opportunity to lead an independent project aimed at developing a new platform to study human risk genes using a chimeric mouse model. This approach would allow me to fully utilize a variety of cutting-edge technologies, and I believed it would be an exceptional opportunity for scientific and professional growth. 

Huijie Huang, PhD from the Huang lab

What are the key areas of research you focus on?
My research focuses on developing novel neuroprotective strategies for Alzheimer’s disease. Current clinical treatments primarily aim to relieve mood-related symptoms, using cholinesterase inhibitors or antidepressants, but these approaches offer only symptomatic relief. The new immunotherapies, such as those targeting amyloid beta plaques, are designed to slow disease progression. However, their clinical efficacy remains limited, patient responses are highly variable, and the treatments are costly.

Given these challenges, there is an urgent need for new therapeutic strategies. Our work investigates genes and proteins that influence the risk of sporadic Alzheimer’s disease, which may lead to broadly applicable, gene-based interventions.

What motivates you about your research?
It’s a combination of curiosity and a desire to make a meaningful impact. Curiosity drives me to ask deeper questions and design more insightful experiments. I also find motivation in the research process itself—troubleshooting challenges encourages critical thinking and fosters collaboration with others.

What do you like about working here?
I love it here! The people are all very kind, and you can get help from colleagues, neighboring labs and core facilities. I’d like to especially applaud our core facilities experts for being so professional and efficient. I never have to wait a long time to get our projects and experiments done.

Another important factor is that Tim is very supportive of his team. We have a quite independent but also collaborative environment among colleagues and mentor. When we need help, he will try his best to collaboratively solve the problem or connect us with people in his network with the right expertise.

How would you describe the culture here?
Collaboration is ingrained in the culture and quite easy. If you want to discuss something, you just stop by other labs and people are open to working together. Also, we are surrounded here by different labs with experts in many fields. This contributes to a culture of constant learning and collaboration.

There also are many resources here for postdocs. There are opportunities to apply for funding, workshops for career development and the highly engaged Sanford Burnham Prebys Science Network that plans networking and social events and addresses concerns raised by postdocs.   

What are your hopes for the next stage in your career?
I truly love science, and would like to continue research on neurodegenerative diseases, and I am preparing myself to be independent as a principal investigator or team leader.

What do you enjoy doing when you’re not in the lab?
I like hiking, cycling and playing table tennis.

Q & A with Postdoctoral Researcher Meena Sudhakaran, PhD, from the Kersten Lab

AuthorCommunications
Date

July 23, 2025

Meet one of our early-career scientists at Sanford Burnham Prebys: Meena Sudhakaran, PhD, a postdoctoral researcher in the lab of Kelly Kersten, PhD. Sudhakaran studies cancer immunology to improve immunotherapy for breast cancer.

When and how did you become interested in science?
I was always curious as a child. When one of my family members was diagnosed with cancer, I grew up watching how it affects people. That made me really interested in how diseases work. I wanted to know the causes and the biological reasons beneath it.

What did you imagine you would be doing professionally, and how did it evolve?
When I was done with my master’s degree, I was sure I wanted to work in industry. I was determined to join a biopharma company where I could make medicines.

I worked as a scientist and as a senior scientist for three and a half years on a team at Biocon in India developing drugs for head and neck cancer. During my time in the company, I realized that I wanted to do a PhD to dive deeper into understanding the biology of cancer and how every cancer type is different.

During my PhD, I was introduced to immune cells and how immune cells affect tumor progression. I wanted to be in a cancer immunology lab for my postdoctoral training, so the Kersten Lab here was a perfect fit.

What are the key areas of research you focus on?
Breast cancer patients do not really respond to most immunotherapy drugs. We don’t yet know why they are ineffective.

Our immune system protects our bodies from pathogens, foreign particles or any abnormal cells like cancer. T cells, a type of immune cells in the tumor environment, can get activated and attack the tumor cells. But what often happens is that they become dysfunctional due to continuous exposure to the immunosuppressive environment and lose their ability to kill. Additionally, there are other immune cells such as macrophages that create a tumor-promoting environment.

Kelly previously showed that macrophages and T cells interact, creating a communication loop where the macrophages drive the T cells to exhaustion. The focus of my research is to understand how this interaction creates an anti-tumor immune response in breast cancer. This will help us get closer to the ultimate goal of making immunotherapy more effective in breast cancer patients.

What do you like about working here?
Kelly is a great mentor. She is very supportive. She is easy to approach, and our discussions are always encouraging yet stimulating. I believe it is really important for a successful lab that trainees feel comfortable discussing ideas and challenges openly.

Outside of my lab, there are lots of shared resources and training opportunities available. Everything is nearby and easy to access. People here are also very open to collaboration, which creates a strong and supportive research environment.

What motivates you about your research?
I love doing research! I like being in the lab, planning experiments and looking at the results.

It’s like solving a puzzle, so that keeps me excited.

What are your hopes for the next stage in your career?
I plan to return to industry and continue focusing on the translational side of biomedical research. My goal is to combine my experience in both industry and academia to help develop new medicines and improve treatments.

Although I am still early in my postdoctoral training, I can already see how much I’m learning. When I go back to industry, I’ll have stronger problem-solving skills, more knowledge, and more confidence in making decisions. I have definitely made progress, and I know that growth will continue and support me throughout my career.

Q & A with Postdoctoral Researcher Ranajit Das, PhD, from the Cosford Lab

AuthorCommunications
Date

July 15, 2025

Meet one of our early-career scientists at Sanford Burnham Prebys: Ranajit Das, PhD, a postdoctoral researcher in the lab of Nicholas Cosford, PhD. Das is a medicinal chemist focused on designing and synthesizing new potential therapies, with a focus on cancer treatment.

When and how did you become interested in science?
During my early childhood education, I developed a deep curiosity about the world around me. Over time, I became more interested in chemistry. I found it fascinating that two colorless things can mix and make something colorful, or that two liquids can merge and produce a solid.

Then, when I was introduced to organic chemistry in my undergraduate years, it was eye-opening. I realized that organic chemistry is connected to nearly everything we use or do in our everyday lives. Everything from the blue dye in denim jeans to fading vegetable colors, fragrances, and even the medicines we take, are made of organic molecules. That realization drew me even deeper into the subject.

As I continued studying organic chemistry, I got into synthetic organic chemistry and building molecules. If you have the right knowledge, you can use simple building blocks that are usually made of carbon, hydrogen, nitrogen, and oxygen, and assemble them into compounds that can be functional, beautiful and even lifesaving.

How has your scientific career evolved?
While earning my master’s degree, I was learning about drug discovery and how organic molecules can be useful for treating human diseases. Then, during my PhD, I trained in how to use those chemical components to build a probe to study a disease and ascertain how to potentially cure that disease.

Ever since, I have wanted to build something which will improve human health. That is the reason I decided to pursue a scientific career.

What brought you to the Cosford lab at Sanford Burnham Prebys?
I chose to pursue my postdoctoral training at Sanford Burnham Prebys because of its strong emphasis on drug discovery. The Cosford lab has been working for almost two decades on a wide range of disease models—including cancer, central nervous system and infectious diseases—which are key areas in today’s therapeutic landscape.

This provides an unusual opportunity to gain practical experience with diverse targets. Furthermore, several of the lab’s drug candidates are in preclinical or phase I/II clinical trials, reflecting its strength in translational research.

What are the key areas of research you focus on?
Apoptosis, or programmed cell death, is a natural process in our body. It allows us to remove unwanted cells as we grow and develop. Cancer, however, can disrupt the system of apoptosis.

One way this happens is through the action of inhibitor of apoptosis proteins, which block caspases and help regulate cell survival and cell death during cancer. The second mitochondrial activator of caspases, or SMAC, can bind to and neutralize these inhibitor of apoptosis proteins, thereby promoting apoptosis.

We’re trying to make molecules that can mimic SMAC in order to treat cancer.

What motivates you about your research?
It’s the creativity and complexity around creating 3D chemical architecture to have potential medicinal properties. As we test and refine the compounds, I enjoy using my knowledge of how they react with protein molecules and how that affects the activity of those proteins, which can be useful for targeting diseases.

It is essential to nurture a feedback loop of biological activity and synthesis that keeps the drug discovery process dynamic and purposeful. For me, it is motivating to see that we are designing something and synthesizing something that is having the biological activity necessary for any potential candidate therapy. From there, we can work on finetuning in terms of potency, selectivity, pharmacodynamic stability and other characteristics of successful treatments.

What do you like about working here?
I like the collaborative and supportive research environment here at the institute. We have scientists and students from many different backgrounds and areas of expertise all focused on the same goal, the advancement of biomedical research.

The core research facilities and interdisciplinary expertise make this place ideal for pursuing very complicated targets for translational research. The Institute also has an emphasis on mentorship and career development, which is very important. I feel I’m growing as a scientist in a community which values curiosity, integrity and teamwork.

How would you describe the culture here?
There is a culture of open communication. Sharing ideas, discussing challenges and seeking feedback are encouraged. I’ve found this helps foster personal and professional growth, as well as scientific innovation.

What do you enjoy doing when you’re not in the lab?
I have a deep appreciation for world cinema, particularly Hollywood classics from the 80s and 90s. Bengali literature holds a special place in my heart, as does Indian classical music—especially the rich, melodic tones of the sitar and sarod.

Q & A with Postdoctoral Researcher Sara Ancel, PhD, from the Wang Lab

AuthorCommunications
Date

July 8, 2025

Shaping the future of science at Sanford Burnham Prebys: Sara Ancel, PhD, a postdoctoral researcher in the lab of Will Wang, PhD, who draws on a background in engineering and stem cell biology to explore tissue remodeling and disease mechanisms through cutting-edge spatial omics approaches. Originally from Switzerland, she brings together cutting-edge technology and collaborative science to push boundaries—and inspire the next generation of researchers.

How did you first become interested in science—and what brought you to Sanford Burnham Prebys? 
I didn’t grow up around science, my parents weren’t in the field, so I didn’t really get exposed to it until high school. But I’ve always been curious, especially about things I didn’t understand. That curiosity led me to study engineering, which gave me the flexibility to explore many scientific fields before focusing on one.

During my master’s studies in Switzerland, I had the opportunity to spend time at Stanford University working in Dr. Helen Blau’s lab. That’s where I met Will Wang, who would later become a principal investigator at Sanford Burnham Prebys. When I was finishing my PhD in Switzerland, he was just starting his lab here. The timing was perfect—and I became his first postdoc.
Shape

What drew you to Will Wang’s research?
What really stood out to me was the new technology he was developing—an imaging method that lets us look at many biological markers at once. Coming from an engineering background, that kind of innovation was really exciting. I saw a chance to combine everything I’d been learning, for example, stem cell biology, muscle research, and engineering, into one meaningful project.

Plus, joining a brand-new lab was a unique opportunity. I was involved in everything from setting up experiments and training newcomers to handling operations. It was a fast-paced, all-hands-on-deck experience that taught me so much, both scientifically and personally.
Shape

What are you working on now? How would you explain it to someone outside of science?
My main project focuses on a process called glycosylation, which is how cells add sugar molecules to proteins and fats. These sugar tags might sound simple, but they play a big role in how cells function, and how things go wrong in disease.

I had no background in glycobiology when I started, but I was able to bring in new technologies and combine them with biology to explore this process in a completely new way. I’ve also been fortunate to collaborate with the Freeze Lab here at Sanford Burnham Prebys, which has been incredibly valuable.

What makes Sanford Burnham Prebys a unique place to work?
I’ve been so impressed by how collaborative this institute is. It’s a small enough community that people know each other, so reaching out for help or advice is easy. I’ve been able to train on equipment here and at nearby institutions like UC San Diego, and I’ve had the chance to connect with researchers across many fields.

One of the most exciting aspects has been working with clinicians and getting access to real patient samples. That kind of experience really deepens the impact of our research and gives me a broader view of how basic science can connect to human health.

What was one of the biggest challenges you faced when you arrived?
Moving from Switzerland to San Diego was a huge adjustment. I arrived and quickly within about a week, I was in a new culture, new lab, and new scientific environment. I was also the only person in the lab at first, which made things more intense.

But I had great support from international services and from the community of researchers here. That support helped me adapt, and it motivated me to dive in and help get the lab up and running.

What do you hope to do next in your career?
I’ve developed a wide range of skills here, not just technical, but also communication and collaboration. I’d love to build on that by moving into work that’s more closely connected to patients. Collaborating with clinicians and working with patient samples has been incredibly meaningful, and I’d like to pursue more translational or clinical science in the future.

What do you enjoy doing when you’re not in the lab?
Since moving to San Diego, I’ve gotten into climbing and bouldering, it’s something I picked up with friends from neighboring labs. I also love hiking and visiting national parks. Coming from Switzerland, I’m used to mountains, but the parks here in the U.S. are spectacular. I’ve started a list and want to see as many as I can!

What advice would you give to young scientists?
Stay curious. Don’t be intimidated by what you don’t know—see it as an opportunity to grow. Science can be frustrating when things don’t work out, but that’s part of the process. If you accept the ups and downs and keep learning, it can be incredibly rewarding.

Do you have any publications or projects in the works?
Yes! I’m finishing a methods-focused paper on the technology I’ve been developing, and we’ve filed a patent on it thanks to support from the Institute’s intellectual property team. I’m also co-authoring a review article with a researcher from Stanford on drug discovery for muscle aging. It’s been a great opportunity to step back and reflect on everything happening in the field.

The Institute’s Graduate School of Biomedical Sciences held its second Commencement ceremony to celebrate four recent graduates

Family, friends and colleagues gathered at the end of May 2025 to applaud the four newest alumni of the Sanford Burnham Prebys Graduate School of Biomedical Sciences. These early-career scientists are the latest graduates to leave their mark on the institute and carry forth the graduate program’s motto, “Knowledge is the power to heal.”

On Friday, May 30, 2025, the Graduate School of Biomedical Sciences held its graduation ceremony at the institute’s La Jolla campus in the Victor E. LaFave III Memorial Auditorium.

“Each of you has made significant contributions to your field of science, created new knowledge and demonstrated the ability to perform independent research,” said Alessandra Sacco, PhD, dean of the institute’s graduate school and professor and director of the Development, Aging and Regeneration Program in the Center for Cardiovascular and Muscular Diseases.

“Today, we celebrate not only your academic journey, but also your years of dedication to get to this point, and the perseverance and intellectual curiosity that enabled you to reach this milestone.”

Following her remarks, Sacco introduced Ryan Loughran, PhD ’24, to speak on behalf of his fellow graduates.

“Graduate school is an experience unlike any other,” said Loughran. “You’re constantly drinking from a fire hose, learning new techniques, running experiments, coding data pipelines, writing and reviewing papers, preparing posters and giving talks.

‘I came to realize that it’s overwhelming by design. Somewhere in that chaos, something incredible happens. You’re forged by the fire. You begin to absorb information with an insatiable hunger. You think more critically and more creatively when confronting problems, and that is the true gift of the PhD experience.”

Loughran turned the podium over to Guy Salvesen, PhD, the inaugural dean of the graduate school, who provided the Commencement address.

“The graduates in front of you display the success of the program,” he said. “More importantly and more fundamentally, though, they have reached this milestone based on the merits of the hard-won accomplishments that they share with their mentors.”

Diane Klotz, PhD, chief learning officer at Sanford Burnham Prebys, then discussed the meaning of the hoods and symbols that are used in Commencement ceremonies. She invited the graduates forward and instructed faculty members to adorn them with the doctoral academic hoods signifying completion of a PhD program.

This year, the following graduates were recognized:

Andrei Osterman, PhD, the graduate school’s vice dean and associate dean of curriculum and a professor in the Center for Metabolic and Liver Diseases, provided the ceremony’s closing remarks.

“While today is primarily a celebration of individual intellectual achievements, it also recognizes your meaningful contributions to and interactions with the scientific community,” he said. “You have grown through peer review and collaborating with others, and these experiences will benefit you wherever your career takes you.”

More on this year’s graduates

Zong Ming Chua, PhD ’24, was born in Singapore. He developed a deep and early interest in biology after reading Darwin’s seminal work “On the Origin of Species” and various books by Richard Dawkins.

At Sanford Burnham Prebys, Zong Ming investigated the mechanisms that link cellular senescence and epigenetics. He discovered a new role of the histone variant H2A.Z R80C. He found that the histone variant influenced the transcriptomic profile of senescent cells.

Zong Ming moved to the Bay Area after graduating and is currently a computational biologist at GigaGen.

Jordan Friedlein, PhD ’24, was born and raised in Minnesota. From an early age, he expressed a desire to understand how the world worked. In high school, biology and physiology were his favorite classes.

Jordan joined the Bagchi Lab in 2019 and worked on investigating the role of circular RNA derived proteins in Myc-driven cancers. During his five years, Jordan enjoyed contributing to cutting-edge research and building lasting relationships with other grad students and institute members.

Ryan Loughran, PhD ’24, was born and raised in Greensburg, Penn. Growing up in a family with four generations of pharmacists, Ryan always imagined following in their footsteps and taking over the family-owned Loughran’s Pharmacy.

However, his path took a different turn during his undergraduate studies when he had the opportunity to spend a summer in New York City as an intern in the Emerling lab at Weill Cornell Medicine. He later moved with Emerling to help establish her new lab at Sanford Burnham Prebys as her lab manager. He later joined the Emerling lab as a graduate student.

Ryan plans to undertake a short postdoctoral position before transitioning into the pharmaceutical industry, where he aims to apply his knowledge and experience in cancer research to real-world applications.

Zhouting Zhu, PhD ’24, grew up in Changzhou city in the Jiangsu province of China. After completing a Master of Science in Surgery degree from Nanjing University in 2018, Zhouting joined the graduate program at Sanford Burnham Prebys.

She conducted her doctoral research in the lab of Tariq Rana, PhD, an educational affiliate professor in the Graduate School of Biomedical Sciences. Zhouting focused on RNA biology and cancer immunotherapy. Her work explored immune cell dynamics in tumors and spleens under various treatment conditions in mouse cancer models.

Zhouting is currently working toward MD-equivalency certification, with the long-term goal of becoming a board-certified physician-scientist.

Sanford Burnham Prebys scientists bring dramatic stories of scientific achievement to life

In March 2025, Sanford Burnham Prebys scientists Ani Deshpande, PhD, and Pamela Itkin-Ansari, PhD, launched a new podcast exploring groundbreaking discoveries in science and medicine. The initial episodes have garnered rave reviews, including being hailed as “masterpieces” by upcoming podcast guest Adam Heller, PhD, the scientist and inventor who revolutionized blood sugar testing and laid the groundwork for modern continuous glucose monitoring systems.

On the first episode of The Discovery Dialogues Podcast, the hosts examined early descriptions of diabetes across ancient civilizations. Deshpande and Itkin-Ansari traced the research that led to the discovery of insulin and to life-saving treatment for diabetes.

Following its discovery as a treatment for diabetes, insulin had to be purified from millions of animal carcasses. In the follow-up episode, the podcasters discussed the race to make human insulin using genetic engineering, including interviews with Keiichi Itakura, PhD, a key member of the historic team that created the first synthetic gene to make human insulin, and Herb Boyer, PhD, the scientist who founded the first biotech company called Genentech and brought insulin to millions of patients.

Pamela Itkin-Ansari, PhD, is an adjunct professor in the Center for Cardiovascular and Muscular Diseases at Sanford Burnham Prebys.

Last week, Deshpande and Itkin-Ansari released their third episode detailing animals that use insulin as venom and highlighting an animal that can sense low blood sugar faster than a machine.

We recently sat down with them to learn more about their motivations and creative process.

What is your origin story as scientists turned podcasters?

DESHPANDE: I have been very interested in communicating science for quite some time. And I think it is important for more scientists to speak in a way that all people can understand, and to embrace new ways of communicating.

I got especially excited to talk about the incredible potential of GLP-1 drugs such as Ozempic and Wegovy, but I don’t think you can properly understand them without a grasp of diabetes. I decided to tackle diabetes as the podcast’s first topic, and I reached out to Pam as a partner with complementary expertise.

ITKIN-ANSARI: I have done a lot of scientific outreach in the past as a diabetes scientist, including with the La Jolla Playhouse and Fleet Science Center, so I jumped at the opportunity. As it turns out, Ani and I are kindred spirits in terms of our desire to help people understand how biomedical research has changed the world.

What is your process for developing each episode?

DESHPANDE: We have a very elaborate process for deciding on each episode’s topic. outlining the chapters or segments and then passing drafts back and forth until we’ve refined them into a version that is both accurate and entertaining.

ITKIN-ANSARI: Getting that balance right is so important. I’m a Radiolab junkie. I have to hear every episode. The reason I keep coming back is because I get to learn something new and have a ton of fun along the way.

DESHPANDE: It is important to us that we’re not just telling stories people already know, so we take our time to find fascinating stories about the science and the personalities behind the discoveries.

How much research goes into making the podcast?

DESHPANDE: We just read and read and read and read. Then, we bounce ideas off each other to see what makes it into an episode.

ITKIN-ANSARI: The other thing is fact-checking. We feel it our job as card-carrying scientists to be as thorough as we can be to get the facts right.

While writing for the first three episodes, what information or stories surprised you?

ITKIN-ANSARI: For me, I was amazed by the venoms of the cone snail that have already led to an FDA-approved drug for severe pain and may also revolutionize diabetes treatment.

DESHPANDE: I think it’s surprising that diabetes had been described in detail more than three millennia ago. Many of our audience members told us they were surprised by that fact as well.

What teasers can you share about future episodes?

ITKIN-ANSARI: For an upcoming episode, a legendary scientist who changed diabetes care forever after surviving the Holocaust and making his way to the U.S.

DESHPANDE: One of the most fascinating things we will cover in our future episodes and that will surprise most people is that many of the most influential drugs in the history of medicine have come from plant poisons and animal venoms. It blows my mind, and I hope our listeners will also find it to be amazing.

The annual Rising Stars Symposium featured nine doctoral-degree candidates representing the next generation of scientists

Nine doctoral-degree candidates from across the U.S. visited Sanford Burnham Prebys for the fourth annual Rising Stars Symposium, a research meeting and networking opportunity for future postdoctoral researchers.

James Marchant, PhD, a postdoctoral fellow in the lab of Alexandre Colas, PhD, at Sanford Burnham Prebys, opened the meeting by introducing the symposium’s keynote speaker, Mark Mercola, PhD, a professor of Medicine at the Stanford University School of Medicine and a professor in the Stanford Cardiovascular Institute.

“We’re so pleased to have a keynote address from a stem cell biology expert responsible for identifying many of the factors that guide the formation of the heart,” said Marchant. “This also is a homecoming for Mark, who was previously on the faculty here and continues to be an extended family member through collaborations and service on dissertation committees.” 

Mercola held a joint appointment as a professor at Sanford Burnham Prebys and the University of California San Diego from 2003-15 before joining Stanford. He began his lecture with a discussion of how his research evolved throughout his career, including the opportunities provided by the discovery of induced pluripotent stem cells. Mercola now focuses on developing treatments for heart failure that target mechanisms rather than symptoms.

“While drugs for heart failure have improved over time, they continue to generally improve heart function by altering conditions such as blood pressure and heart rate rather than target the underlying causes,” said Mercola. “I envision a day when treatment begins to resemble modern cancer therapies that are targeted based on understanding characteristics of tumors.”

Mercola also offered career advice to the Risings Stars. He emphasized the importance of pursuing a long-term vision that can guide how you seek training, apply for funding and build your network. Mercola suggested that this vision needs to be balanced with measurable short-term goals that can show your intermediate progress along the way. He also implored early career scientists not to stay isolated in their own labs.

“Be collaborative, and you’ll find that the work is always more enjoyable and successful when you are part of a team,” said Mercola.

Following the keynote address, four Rising Stars discussed their research projects:

  • Paola E. Peña García, a PhD candidate in the Poynter lab at the University of Vermont
  • Jaquesta Adams, a PhD candidate in the Landry lab at the University of California Berkeley
  • Michell Carroll, a PhD candidate in the Pattenden lab at the University of North Carolina Eshelman School of Pharmacy
  • Janice Reynaga, a PhD candidate in the Blanco lab at the University of Pennsylvania

Lukas Chavez, PhD, an associate professor in the Cancer Genome and Epigenetics Program at Sanford Burnham Prebys, offered concluding remarks at the end of the symposium’s first day.

“With their excellent presentations, our Rising Stars have lived up to their name,” said Chavez. “It is exciting and reassuring to see that the next generation of biomedical research is in capable hands.”

David Brenner, MD, the president and chief executive officer of Sanford Burnham Prebys, began the symposium’s second day by sharing an overview of the institute and San Diego’s scientific community.

“There is something special in the intellectual environment here at Sanford Burnham Prebys and our neighboring research institutions,” said Brenner. “If you conduct a postdoctoral fellowship here, you will find it to be a very welcoming, collaborative and interactive ecosystem.”

Sanju Sinha, PhD, an assistant professor in the Cancer Metabolism and Microenvironment Program at Sanford Burnham Prebys, added his reflections on the importance of scientific meetings for early career researchers.

“I place great value on these kinds of symposia,” said Sinha. “I met many of my collaborators at a similar symposium in New York, so I encourage the Rising Stars to take advantage of this opportunity to get to know each other and investigators throughout the institute.”

After the opening remarks, five Rising Stars presented about their research:

  • Lanette LaComb, a PhD candidate in the Almo lab at the Albert Einstein College of Medicine
  • Danielle Johnson, a PhD candidate in the Jewett lab at the University of Arizona
  • Tracey Porter, a PhD candidate in the Wingert lab at the University of University of Notre Dame
  • Sarah Brashear, a PhD candidate in the Smith lab at the University of California Davis
  • Ariell Smith, a PhD candidate in the Eguiluz lab at the University of University of California Merced

In addition to the two days of scientific talks, the Rising Stars toured the Conrad Prebys Center for Chemical Genomics, learned about the institute’s core facilities and shared research resources, networked with institute scientists, and gained a better understanding of postdoctoral opportunities at Sanford Burnham Prebys.

The 2025 Rising Star Symposium was sponsored by the NCI-designated Cancer Center and was planned collaboratively by the institute’s Workforce Engagement and Belonging Council and planning and selection committees.

The planners expressed their gratitude to everyone who contributed to this institute-wide effort, including session moderators and facilitators, Cancer Center administration, the Research Administrative Services team, the Communications team and many volunteers.
