Meet one of our early-career scientists at Sanford Burnham Prebys Medical Discovery Institute: Bastien Cimarosti, PhD, a postdoctoral researcher in the lab of Sanjeev Ranade, PhD. Cimarosti studies how the heart forms and what causes congenital heart defects.

When and how did you become interested in science?
For as long as I can remember, I’ve always been curious about the world around me. For example, when I was growing up, I loved to visit castles from the Middle Ages to understand more about our history or read books about physics and engineering.

During high school, I fell in love with biology thanks to a couple of teachers. Later I went to medical school, and it made me appreciate even more that there are so many things we don’t understand yet about human biology. That led me to a research career where I could explore my curiosity about the unknown.

What are the key areas of research you focus on?
I have a lot of different projects, but they all have in common that we are trying to understand what leads to babies being born with congenital heart defects. And how these conditions will affect patients throughout their lives.

Thanks to advances in medicine and surgical practice, most children born with congenital heart defects will reach adulthood. Even after surgery, however, the disease is still present and affects how patients develop and age over time.

We still have a lot to learn about what causes congenital heart defects. By better understanding the genetic or environmental factors at play, perhaps one day we will be able to prevent the disease from occurring in the first place.

What motivates you about your research?
On a day-to-day basis, my motivation is to do the basic science we need to understand how the heart forms and how perturbations during pregnancy can affect the heart.

Also, I use a lot of what are called omics techniques that can capture the complexity of living systems. I’m using different bioinformatics tools and machine learning tools to analyze the large datasets produced by these techniques. Because the datasets are so wide and capture a large portion of the underlying biology, I like that I am never stuck and can switch very quickly between ideas based on what I see in the data.

What do you like about working here?
The training environment for postdocs is just amazing. The core research facilities are tremendous as well. I work a lot with the genomics core and the experts there are terrific. You can just keep advancing science without thinking about technical constraints because everything you need is on campus and available to you.

What I love the most, though, is being with my lab. I love being able to work with my mentors, peers and colleagues, and being surrounded by smart and talented people.

What are your career goals?
My goal is to stay in academia, become a principal investigator and open my own lab. I would like to continue working on cardiac developmental biology and how cardiac diseases develop.

What do you enjoy doing when you’re not in the lab?
I love nature and being outside. I love hiking in the mountains around San Diego, going to the beach and swimming. And I look forward to meeting up with friends whenever we can to explore national parks together.

Postdocs at Sanford Burnham Prebys are pushing the boundaries of science every day through curiosity, collaboration, and innovation. This series highlights their unique journeys, what inspires their work, and the impact they’re making across our labs.

Cosimo Commisso awarded $110,000 Lustgarten Foundation grant for pancreatic cancer research

The new award will fund investigation into a method for turning a tumor survival mechanism into a Trojan Horse

Cosimo Commisso, PhD, was awarded a one-year, $110,000 Lustgarten Foundation grant to support his lab’s pancreatic cancer research. The award is part of the foundation’s August 2026 announcement of $22.8 million in new research funding in fiscal year 2026.

The Lustgarten Foundation’s support will aid the Commisso lab’s study of how pancreatic cancer adapts as nearby nutrients vanish. Because they expand quickly, pancreatic tumors demand more energy and other resources than they can acquire from nearby blood vessels.

Rather than limiting their growth to more sustainable rates, these cancer cells adapt by finding alternative ways to scavenge what they need. One scrounging strategy prevalent in pancreatic cancer involves cancer cells reshaping their cell surfaces to snatch extra nutrients from the jelly-like substance between cells or extracellular matrix.

This cellular contortion is a process called macropinocytosis. In previous research, Commisso has shown that blocking it cuts tumors off from needed energy and protein building blocks. This, in turn, suppresses tumor growth by essentially starving the tumor.

The new funding will support the lab’s effort to flip the script on this strategy. Instead of blocking macropinocytosis, the scientists will test turning up the knob on a tumor’s voracious appetite for scavenging to cause it to self-destruct from overconsumption. This approach also may be able to force cancer cells to take in more chemotherapeutic molecules, which can struggle to penetrate the dense and fibrotic tumor microenvironment.

“This project has the potential to turn one of pancreatic cancer’s greatest survival tools into a Trojan Horse,” said Commisso.

“Support from organizations like the Lustgarten Foundation encourages us to ask fundamentally new questions in the pursuit of better therapies.”

With the fiscal year 2026 awards, the Lustgarten Foundation has invested $333 million in pancreatic cancer research across 386 projects at 86 academic institutions since 1998. As the world’s largest private funder of pancreatic cancer research, the foundation drives scientific breakthroughs that are redefining what is possible for patients and bringing the field closer than ever to the goal of transforming pancreatic cancer into a curable disease.

From the Lab to the Clinic: Graduate Student Helps Advance Promising Pancreatic Cancer Therapy

When Patrick Hagan joined Sanford Burnham Prebys as a graduate student, he hoped his research would one day help patients. Today, he is helping research that could translate more than a decade of scientific discovery into a potential new treatment for one of the deadliest forms of cancer.

Hagan, a PhD candidate in the laboratory of Nicholas Cosford, PhD, recently received the top award from the San Diego chapter of Nucleate, a nonprofit organization that helps scientists translate promising discoveries into real-world solutions.

Through the six-month accelerator program, Hagan developed ATG Attack, a venture focused on advancing autophagy inhibitors for pancreatic cancer. The project also received a Biocom Golden Membership at Nucleate San Diego’s Demo Day, recognizing both the scientific promise of the work and its potential to improve outcomes for patients.

“Ultimately, the goal is to improve outcomes for cancer patients,” said Hagan. “That’s why I went to graduate school.”

The project builds on more than 10 years of collaboration between Cosford and director of the Salk Cancer Center, Reuben Shaw, PhD. Together, the teams have been developing compounds that inhibit autophagy, a cellular recycling process that many cancer cells depend on for survival.

“Autophagy is one of the ways cancer cells gain resistance to standard therapies,” Hagan explained. “We’ve reached a point where we believe these compounds have the potential to make it all the way to patients.”

The team’s initial focus is pancreatic cancer, a disease with one of the lowest survival rates among major cancers. Many pancreatic tumors are driven by mutations in the KRAS gene and rely heavily on autophagy. In preclinical studies, the researchers have shown that blocking this process can shrink tumors and enhance the effectiveness of existing treatments.

The experience also reinforced the value of Sanford Burnham Prebys’ translational research environment.

Hagan credits Cosford and colleagues throughout the Institute, including members of the Center for Therapeutics Discovery and its Conrad Prebys Center for Chemical Genomics, with helping shape his approach to drug discovery.

“I’ve been fortunate to work with scientists who are deeply focused on translating discoveries into therapies,” he said. “Our lab operates almost like a small pharmaceutical company. We have chemists creating compounds, biologists testing them and researchers evaluating how they perform in disease models. Everything is focused on moving promising discoveries closer to patients.”

For Hagan, however, the motivation remains personal.

He keeps a Post-it note on his laptop bearing the names of two researchers he knew who died from cancer at a young age. It serves as a daily reminder of why the work matters.

“Research can feel like a series of very small steps,” he said. “But every experiment, every paper and every collaboration has the potential to move the field forward. If something we do helps another scientist, attracts a new partner or ultimately helps a patient, then it’s worth it.”

For Hagan, those small steps are all part of a larger goal: bringing new hope to patients facing pancreatic cancer.

Eleven participants completed six weeks of hands-on biomedical research at Sanford Burnham Prebys

Sanford Burnham Prebys Medical Discovery Institute welcomed its fifth cohort of interns this year for the Summer Program to Accelerate Regenerative Medicine Knowledge (SPARK). SPARK is an initiative by the California Institute for Regenerative Medicine (CIRM) that provides research opportunities for high schoolers from underrepresented groups throughout California.

The SPARK participants completed six-week internships at Sanford Burnham Prebys and completed projects under the supervision of their faculty mentors.

“My experience was amazing right from the get-go,” said Jonathan Wang, a rising senior who worked in the lab of Shengjie Feng, PhD. “The whole lab came to greet me on my first day and it was really inviting.”

“It was all very new to me as both my first research experience and my first internship,” said Tannishtha Dhar, a rising junior who worked in the lab of Kelly Kersten, PhD. “I’ve always wanted to be a clinician or surgeon, but now I have a growing interest in biomedical research as well.”

In the first of two capstone events, the interns delivered poster presentations at the Sanford Burnham Prebys campus on July 30, 2026. The students detailed their projects and what they had learned over the course of their internships.

“Beyond what I learned about progressive liver disease in my project, I’m walking away with a greater appreciation of the importance of communication,” said Shiva Ambatipudi, a rising junior who worked in the lab of Debanjan Dhar, PhD. “With lab meetings every week, I saw how valuable it was to be able to share the results of your experiments and make connections with each team member’s work.”

The SPARK internship culminated with CIRM’s annual SPARK conference at the University of California Berkeley from July 31 to August 1, 2026. The participants from Sanford Burnham Prebys presented their work and networked with more than 110 interns from other institutions across the state.

“Being a part of the CIRM symposium was a great way to become more confident in your skills as a scientist,” said Rishab Ghosh, a rising junior who worked in the lab of Timothy Huang, PhD. “I think that growing your personal network and learning how to collaborate with other researchers also are very important aspects of this program.”

“I’m simply blown away at the quality of the work completed by these SPARK interns over six weeks,” said SPARK program director Sanjeev Ranade, PhD. “It was incredibly rewarding to help guide these bright, curious and ambitious students.”
