Research Summary

I am a physician-scientist in the Division of Hematology/Oncology and an attending in the Genitourinary Medical Oncology Clinic at UCSF. I am broadly interested in cancer biology and translational oncology. I completed my postdoctoral research fellowship with Dr. Felix Feng and Dr. Alan Ashworth at the UCSF Helen Diller Family Comprehensive Cancer Center. Our current research projects include investigating the role of CDK12 in prostate cancer, understanding resistance mechanisms to antibody-drug conjugates, and identifying novel surface protein targets for prostate and bladder cancers. I completed my PhD dissertation with the late Dr. Zena Werb, and studied transcriptional regulation of metastasis and the tumor microenvironment.
