Research

Overview

My primary areas of research interest over the years have been in the design, conduct, and analysis of Phase I, II, and III clinical trials evaluating new therapeutic agents and modalities in solid tumor patients. My focus has changed in that I am currently mentoring and assisting junior faculty with their clinical trials as opposed to writing and coordinating my own trials. I am currently focusing on inpatient cancer care.
