Wesley J. Marrero

Overview

Professor Marrero's research interest lies at the intersection of operations research and statistics, with an emphasis on stochastic simulation and optimization to support decision making in practice. His current work addresses various application areas, including substance use disorder, cardiovascular disease, and organ transplantation. Through this research, Marrero has ongoing collaborations with the Massachusetts General Hospital, the University of Michigan Medical School, the University of Michigan School of Public Health, and the US Department of Veterans Affairs. Before joining Dartmouth, he was a postdoctoral research fellow at the MGH Institute for Technology Assessment and Harvard Medical School.
