Professor Marrero’s research interest lies in developing decision-support tools that consider the challenges associated with their implementation in practice, such as inequity, irrational behavior, lack of interpretability, and need for flexibility. To this end, he designs and applies techniques from operations research, statistics, and algorithmic fairness, with an emphasis on simulation and optimization. His current work focuses on measuring and mitigating the effects of bias and inequity through statistical and optimization methods. Through this research, Dr. Marrero has ongoing collaborations with Dartmouth Health, the Geisel School of Medicine, the Massachusetts General Hospital, the University of Michigan Medical School and School of Public Health, and the U.S. Department of Veterans Affairs. Outside of work, he enjoys traveling, hiking, and running.
