Assistant Professor of Surgery

My research is primarily focused on clinical investigations in the diagnosis, treatment and surveillance of patients with peritoneal metastases from a variety of primary tumors. As a surgical oncologist who treats patients with this condition by performing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC); I am interested in better understanding the disease processes, predicting short- and long-term outcomes, and improving treatments in this disease. I am seeking to better understand the the immunologic, genetic, histopathologic, and clinical landscape of these tumors by investigating the natural history, clinical factors, banked tumor tissue, and blood collected from patients with peritoneal metastases. I am attempting to use this data to predict various outcomes - including complications of treatment, ability to perform effective treatment, progression from primary tumor to peritoneal dissemination, disease recurrence, and death – using carefully curated clinical data from UCSD and beyond. Finally, I am attempting to improve treatments of this disease by investigating novel treatments in clinical trials and reviewing the efficacy of existing therapies.

I am also interested in the clinical investigation of cutaneous malignancies – primarily melanoma. I am collaborating on multiple clinical trials of novel therapies for these tumors and am assisting with an autologous tumor infiltrating lymphocyte program at UCSD.
