Research Summary

My primary clinical and research interests focus on gastrointestinal malignancies, where I have developed and led multiple clinical trials, both within UCSF and across multiple sites nationwide and overseas. I am interested in the development and evaluation of new therapeutic agents ranging from novel cytotoxics to molecular targeted agents to immunotherapies, with a particular emphasis on evaluating these in patients with pancreatic cancer. This work has entailed collaborating with laboratory-based investigators on the correlative/translational science to identify individual patient/tumor characteristics that influence prognosis and response to specific therapies, including both tissue- and blood-based biomarkers. Other university responsibilities include leading the site committee for gastrointestinal cancer-specific clinical trial development at the UCSF HDFCCC and serving as chair of the scientific Protocol Review Committee. Nationally, I have served on the scientific program committee, grants committee, and specialty editorial board for the American Society of Clinical Oncology (ASCO), sit on the editorial board for multiple peer-reviewed oncology journals, and am currently a member of NCI’s Pancreatic Cancer Task Force and the NCCN Pancreatic Cancer guidelines committee.
