Research Summary

I am an Assistant Professor and Physician Scientist in the Department of Radiation Oncology at the University of California-San Francisco (UCSF), where I specialize in the treatment and investigation of adult and pediatric brain tumors. Eighty percent of my time is protected for laboratory research, and I am also therefore a Principle Investigator in the UCSF Department of Neurological Surgery Brain Tumor Center. My research examines how developmental signaling pathways function in cancer with the overall objectives of shedding light on the fundamental mechanisms of developmental biology, and identifying novel biomarkers and therapeutic targets to improve patient outcomes. To accomplish those goals, my laboratory makes use of biochemistry, molecular biology, cell biology, mouse genetics, genomics, bioinformatics and pharmacology. Our work has identified novel activators and effectors of oncogenic Hedgehog signaling in medulloblastoma, and revealed a FOXM1/WNT signaling axis that underlies meningioma proliferation. Each of these discoveries serves as the foundation for clinical trials of molecular therapy in medulloblastoma and meningioma patients that are currently under development.
