Feng lab member Alexandra Houser impressed the judges with her pitch on the importance of turning off brain cells

Turning off neurons in our brain is just as important as turning them on, according to third-place Postdoc Pitch Competition contestant Alexandra Houser, PhD.

Houser, a postdoctoral associate at Sanford Burnham Prebys Medical Discovery Institute in the Feng lab, discussed how our ability to have complex thoughts is due to a sequence of on and off signals—akin to a version of Morse code—that neurons use to communicate to one another. She studies proteins called voltage-gated potassium channels that are an important facilitator of these neuron-to-neuron interactions.

Better understanding of the structure of these proteins—and how it changes in aging or in diseases such as epilepsy—may help future scientists develop new treatments.

Joining Houser at the contest was fellow Sanford Burnham Prebys scientist Jessica Proulx, PhD, a postdoctoral associate in the Adams lab. She presented her work regarding how aging interferes with the harmonious balance of transcription factors and chromatin regulators that control which genes are turned on or off in different types of cells.

Proulx shared the team’s success in restoring the activity of a master transcriptional regulator of liver cell identity—HNF4 alpha—using viral-mediated gene delivery tools. This approach may underpin future treatments for age-associated liver dysfunction.

Houser and Proulx were selected to participate in the inaugural Mesa-wide Postdoc Pitch Competition held at Sanford Burnham Prebys on October 23, 2025, after being named the two best presenters at the qualifying event for the institute’s postdoctoral researchers on September 30.

June 4, 2025

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.

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.

April 1, 2025

Two scientific meetings in late March brought together researchers studying aging and its implications for disease

Scientists from San Diego and across the United States gathered March 26-27, 2025, to discuss the latest advancements in aging research. The NIH-funded San Diego Nathan Shock Center, a collaboration among the Salk Institute for Biological Studies, Sanford Burnham Prebys and the University of California San Diego, opened the two scientific meetings with its 2025 symposium on Wednesday, March 26, at the Salk Institute in the Conrad T. Prebys Auditorium in La Jolla.

The event focused on the center’s primary research area, “The Heterogeneity of Aging.” Just as people and organisms age at different rates, scientists have demonstrated that tissues also age at their own speeds – even some cells within tissues age at a unique pace. This phenomenon, known as heterogeneity of aging, is of great interest to researchers as it may hold clues for how to develop interventions that enable people to lead healthier lives as they age.  

The San Diego Nathan Shock Center Symposium convened 193 in-person attendees and another 113 virtual participants over Zoom.

Shanshan Yin, PhD, a postdoctoral associate in the lab of Peter D. Adams, PhD, director and professor in the Cancer Genome and Epigenetics Program at Sanford Burnham Prebys, presented an update on her research regarding breast cancer and aging. She discussed results from investigating changes in gene expression and immune system activity in breast cancer tumors as mice age, leading to increased cancer incidence. Yin was awarded a San Diego Nathan Shock Center pilot grant in 2023.

The 8th annual La Jolla Aging Meeting was held on Thursday, March 27, also in Salk’s Conrad T. Prebys Auditorium. The event brought together 257 in-person attendees and featured mostly short talks from San Diego-based postdoctoral fellows and students researching the biology of aging.

Kelly Yichen Li, PhD, a postdoctoral associate in the lab of Kevin Yip, PhD, interim director of the Center for Data Sciences and professor in the Cancer Genome and Epigenetics Program, delivered a talk regarding her work on zombie-like senescent cells that persist but no longer divide like most normal cells. Li discussed her work exploring cell types in samples of liver tissue. She discovered differences in cell composition and gene expression based on the age of the samples. Li and her collaborators continue to work on methods to identify senescent cells in tissue samples, which would accelerate research in the field.

Tatiana Moreno, a graduate student in the lab of Caroline Kumsta, PhD, associate dean of Student Affairs in the Graduate School of Biomedical Sciences and assistant professor in the Center for Cardiovascular and Muscular Diseases, detailed her studies regarding aging and the body’s cellular recycling system, a process called autophagy. Moreno discussed her findings measuring autophagy in blood samples drawn from human volunteers of various ages, including results regarding the effects of a 12-week exercise program.

Rouven Arnold, PhD, a postdoctoral associate in the Adams lab at Sanford Burnham Prebys, presented his work seeking to better understand how aging can lead to a loss of the unique cellular identity that allows cells to carry out specialized functions in different organs. Arnold focused on the HIRA protein, one of the histone chaperones responsible for helping to build spools out of histones used to hold DNA like a thread. Following studies of HIRA’s role in the aging liver, his results suggest that HIRA plays a protective role to preserve liver cell identity and promote healthy aging in the liver.

Alessandra Sacco, PhD, professor and director of the Development, Aging and Regeneration Program in the Center for Cardiovascular and Muscular Diseases at Sanford Burnham Prebys, and dean of the institute’s Graduate School of Biomedical Sciences, was a cohost for both events. Adams was a cohost for the La Jolla Aging Meeting.


About the San Diego Nathan Shock Center 
The San Diego Nathan Shock Center (SD-NSC), led by Gerald Shadel, PhD, Audrey Geisel Chair in Biomedical Science and professor in the Molecular and Cell Biology Laboratory at the Salk Institute, was established in the fall of 2020 with the overall goal of understanding the heterogeneity of aging in order to allow development of personalized interventions to increase the number of years of healthy life.

To this end, the center provides three novel scientific Research Resource Cores to develop new human cell models of aging and enable the integrated analysis of molecular, cellular and tissue heterogeneity. The SD-NSC also supports and advocates basic biology of aging research in general through the development, training and mentoring activities of a Research Development Core and robust outreach efforts. All of these activities are accomplished via a consortium of three premier research institutions on the La Jolla Research Mesa: the Salk Institute for Biological Studies, Sanford Burnham Prebys and the University of California San Diego.

Alessandra Sacco serves as director of the SD-NSC Research Development Core and Peter Adams serves as co-director of the SD-NSC Heterogeneity of Aging Core.

Getting to know Nowruz at Sanford Burnham Prebys

AuthorGreg Calhoun
Date

March 26, 2025

Attendees at last week’s event welcomed the arrival of spring and learned about this holiday’s traditions and flavors

Just one day after the Northern Hemisphere’s vernal equinox, the institute held an event on Friday, March 21, 2025, in Chairmen’s Hall to raise awareness of an ancient and enduring celebration of spring called Nowruz, or Persian New Year.

The tradition began in the Persian Empire more than 3,000 years ago and continues today. With roots in one of the world’s oldest monotheistic religions, Nowruz started as a sacred Zoroastrian commemoration of life, the rebirth of nature and the triumph of light over darkness.

Nowruz — “new day” in Persian — has transformed over thousands of years into a set of secular customs practiced by many communities. Thanks to the efforts of a dozen members of the United Nations, Nowruz is recognized by UNESCO’s Intangible Cultural Heritage of Humanity effort to recognize and safeguard the invaluable role of cultural customs in bringing human beings closer together and ensuring exchange and understanding among them.

These traditions include a spring-cleaning ritual called khaneh tekani, or “shaking the house,” as well as a dancing event on the eve of the Wednesday prior to the equinox called Chaharshanbeh Suri or “Scarlet Wednesday.” Participants leap over fire and streams to cleanse themselves from the past year’s negativity.

Nowruz celebration lunch

Nowruz at Sanford Burnham Prebys included digital posters describing the celebration and its cultural practices. It also featured another notable tradition known as the Haft-Seen table, which includes items that symbolize different forms of hope for the new year. With “haft” meaning “seven” in Persian, there are seven foundational items that all start with the Persian letter ‘S’ or “seen.” These are:

  • sabzeh (sprouted wheat, barley or lentils)
  • samanu (sweet pudding made from wheat germ)
  • senjed (dried oleaster fruit, also known as lotus tree fruit)
  • seer (garlic)
  • seeb (apples)
  • serekh (vinegar)
  • somagh (sumac, a spice that symbolizes the color of sunrise)
Mehran Ghafari playing a santoor

Nowruz attendees also enjoyed customary food and santoor music provided by Mehran Ghafari, PhD, a postdoctoral associate in the lab of Xiao Tian, PhD, an assistant professor in the Center for Neurologic Diseases at Sanford Burnham Prebys.

This event was a continuation of the Holidays Around the World series at Sanford Burnham Prebys. This series is planned by volunteers from labs and departments across campus, the Workforce Engagement and Belonging Council and the Office of Workplace Engagement and Belonging. The goal is to bring the Sanford Burnham Prebys community together to learn more about the many cultures represented within the institute’s faculty, staff and trainees.
