Today, we have the pleasure of introducing Dr. Jessica Foster through an engaging Q&A session. Dr. Foster is a distinguished clinician and researcher, dedicating her expertise to both patient care and groundbreaking research endeavors. With over a decade of experience at the Children’s Hospital of Philadelphia, her focus lies in pediatric brain and spinal cord tumors. Driven by a passion for improving outcomes, she and her team are pioneering innovative approaches, including leveraging the immune system to combat these challenging cancers.


Join us as we delve into Dr. Foster's journey, her pioneering work, and the profound motivation behind her dedication.



Q: What led you to specialize in pediatric brain cancer research & treatment?


Dr. Foster: I was intrigued by both the brain and cancer from an early age, starting in high school. My major in college was neuroscience, and it was during college I decided to pursue a career in medicine, and I was already drawn to pediatric oncology. This interest never waivered during my residency, and I ultimately chose the Children’s Hospital of Philadelphia (CHOP) for my fellowship training so I could learn more about the cutting-edge CAR T cell technology. Once I arrived at CHOP I finally put all my passions together, focusing on pediatric neuro-oncology and researching novel immune-based therapies, specifically focusing on CAR T cells for central nervous system tumors.


Q: As both a clinician and a researcher, how do you balance the emotional challenges of working with pediatric patients with the scientific and medical aspects of your job?


Dr. Foster: I am never more motivated to get back into the lab and help find a cure than after my time attending on the inpatient service. Seeing patients directly inspires me to ask more questions and try to find better answers. As a mother myself, taking care of pediatric patients can hit quite hard emotionally. I try to use that as fuel to work harder and push our research forward, faster.


Q: How do you stay hopeful and positive in the face of such a challenging disease?


Dr. Foster: I believe we are on the cusp of dramatically changing the outcomes for patients with CNS tumors. Looking back at pediatric oncology history, the treatment of leukemia changed over the course of a few decades with a deeper understanding of the cancer’s biology and well-run, large-scale, clinical trials. We are now at that point for pediatric CNS tumors where we are truly understanding the biology of all the diverse tumor types and using that knowledge to design thoughtful trials.


Q: How do you incorporate research findings into your clinical practice?


Dr. Foster: I am constantly scouring the literature for new data for all of my patients. For many, there is a standard of care therapy and I will always use that first and foremost. Even our standards of care are constantly changing based on the latest research. For others either without standard of care or who have relapsed, I try to see what biological insights we are gaining for their tumor type, and if there any open trials that seem to target the tumor best. If no trials are available, I will look to see if there are other drugs available either commercially or through expanded access that might help.


Q: What are your hopes for the future of pediatric brain cancer research and treatment?


Dr. Foster: My hope is that I never have to tell a family that we have no options for their tumor. I personally hope that immunotherapy becomes a mainstay of treatment and that we can improve access for all of our novel therapies across the globe.


Q: Outside of work, what are some of your interests and hobbies?


Dr. Foster: My husband, two children, and I love to go skiing in the winter and swimming in the ocean or lake in the summer. I am an avid Phillies fan, so you can find me at Citizens Bank Park quite a bit sporting a Realmuto jersey. I also enjoy traveling and running with friends.

LBF's Transformative Partnership with CBTN Drives Groundbreaking Advances Brain Cancer Research
March 12, 2025
The Lilabean Foundation (LBF) has played a vital role in advancing pediatric brain cancer research, providing significant support to the Children’s Brain Tumor Network (CBTN) based at the Children’s Hospital of Philadelphia. From its origins as a small family foundation, LBF has grown into one of the most influential contributors to CBTN, driving innovative research and achieving new milestones in philanthropy. One of the most notable impacts of LBF’s support is its investment in Project Accelerate, an initiative designed to expedite research and enhance the Pediatric Brain Tumor Atlas. Through LBF’s backing, CBTN has been able to recruit essential data engineers and bioinformaticians, improving research methodologies and strengthening data models. This investment has helped break down silos and create more robust predictive models, optimizing diagnostic accuracy and advancing AI technology. This initiative is positioning CBTN to achieve transformative breakthroughs in precision care and treatment for pediatric brain tumors “The impact of The Lilabean Foundation's generosity cannot be overstated,” said Dr. Adam Resnick, Scientific Director of the Children’s Brain Tumor Network.” “With this partnership, we are paving the way for the next era of pediatric brain cancer treatment and care. Thanks to this continued support, we are one step closer to ensuring that children with brain tumors have the best possible outcomes.” Maximizing Research Potential and Driving AI Innovation: LBF’s contributions have also been instrumental in maximizing the impact of the National Institutes of Health’s (NIH) data generation initiative. With LBF’s support, CBTN was able to extract and ship over 7,000 specimens, enabling the standardization of critical molecular data. This data has formed the foundation for AI-driven technologies, putting CBTN at the forefront of AI research and allowing for discoveries that were once unimaginable. By integrating clinical, molecular, and imaging data into a single multimodal dataset, this collaboration is enhancing the ability to create more individualized and effective treatment plans for children with brain tumors. “The integration of this multimodal data is a game-changer,” said Nicole Giroux, Executive Director of The Lilabean Foundation. “It has the potential to dramatically improve how we understand and treat pediatric brain tumors.” Preparing for Future Breakthroughs: With LBF's continued support, CBTN is now poised for its next big leap in research. The foundation’s investment in Project Accelerate has led to the creation of an extensive multimodal dataset, which was instrumental in securing a first-of-its-kind award from the Advanced Research Projects Agency for Health (ARPA-H). This prestigious award, focused on pediatrics, combined with a new partnership with Amazon Web Services, positions CBTN for major advancements in AI capabilities and further opportunities for breakthrough research. A Legacy of Impact: LBF’s sustained commitment to CBTN is a testament to the power of philanthropy and the profound impact that a dedicated donor community can have on children’s healthcare. Their investments have not only laid the groundwork for groundbreaking research but are also shaping the future of pediatric brain tumor treatment and care, from bench to bedside. “We are incredibly grateful for the support of The Lilabean Foundation,” said Jena Lilly, executive director of CBTN. “Their partnership has been invaluable in driving forward our shared mission to improve the lives of children battling brain tumors. Together, we are creating a future where cures and better treatments are within reach.”
