Research Summary

I am the Director of Basic Science in the UCSF Brain Tumor Center, the Vice-Chairman of the UCSF Department of Neurological Surgery, and a co-PI of the UCSF Brain Tumor SPORE. I am a recognized expert in the areas of cell signaling, temozolomide-based drug resistance, and gliomagenesis. As the Suzanne Marie Haderle and Robert Vincent Haderle Professor of Molecular Neuro-Oncology, I direct a lab that focuses on genetic events that drive brain tumor formation and drug resistance and that in turn may serve as targets for the development of new therapies for brain tumors.
