Marni J. Falk, MD

Marni J. Falk

Dr. Falk is a Clinical Geneticist who serves as executive director of the Mitochondrial Medicine Frontier Program. Her translational research lab investigates the causes and global metabolic consequences of mitochondrial disease, as well as targeted therapies, in C. elegans, zebrafish, mouse, and human tissue models of genetic-based respiratory chain dysfunction.


Carolyn A. Felix, MD

Carolyn A. Felix

Dr. Felix uses molecular, biochemical, cellular and in vivo methods to investigate the pathobiology of leukemias with KMT2A (MLL) translocations. Leukemias with these translocations affect infants and young children or occur as a complication of type II topoisomerase (TOP2) poison chemotherapies used for anti-cancer treatment. She aims to develop better treatment and prevention approaches for these leukemias, which have a poor prognosis.


Alan W. Flake, MD

Alan W. Flake

Dr. Flake is a general pediatric surgeon with a clinical and research focus on prenatal treatment ranging from the fetal surgical repair of anatomic anomalies to prenatal stem cell and gene therapy. He has extensive experience in developing rodent, canine, and sheep models for in utero transplantation and for investigating fetal surgery for anatomic malformations.


Jessica B. Foster, MD

Jessica B. Foster

Dr. Foster’s current research focuses on immunotherapy for pediatric solid and brain tumors. Specifically she is investigating chimeric antigen receptor (CAR) T cell therapy for neuroblastoma, high-grade gliomas, medulloblastomas, diffuse intrinsic pontine gliomas, and other brain tumors. The goals of her research are to develop pre-clinical CAR T cells for translation into clinical trials to help these devastating tumors.


Jason L. Freedman, MD, MSCE

Jason L. Freedman

Dr. Freedman has a particular interest in epidemiologic and translational research within pediatric supportive oncology. He aims to advance the understanding and treatment of symptoms, infections, and organ toxicities in pediatric cancer and hematopoietic stem cell transplant patients.


Deborah L. French, PhD

Deborah French

Dr. French came to CHOP in 2008 to establish the Human Pluripotent Stem Cell Core in the Center for Cellular and Molecular Therapeutics. She is an internationally recognized researcher involved in multi-investigator teams that utilize pluripotent stem cells for modeling human disease to study mechanism, development, and establish new therapeutic modalities.
