Diego A. Martínez is an assistant professor of emergency medicine and health sciences informatics at the Johns Hopkins University School of Medicine.

Dr. Martínez’s research focuses on systems design and optimization, with applications in medical decision-making, infectious disease dynamics, healthcare operations, and health policy. The guiding principle for his research is that a well-designed health system must be based on a sound mathematical model. His research utilizes a wide range of techniques including statistical and machine learning, Markov models, Bayesian inference, network science, optimization, and game theory.

Dr. Martínez obtained his BS (2010) in industrial engineering, summa cum laude, at the University of La Frontera, Chile, and his MS (2011) and PhD (2015) at the University of South Florida, where he worked with Jose Zayas-Castro in operations research and health systems. From 2015 to 2017, Dr. Martínez was a postdoctoral research fellow with the Johns Hopkins Center for Data Science in Emergency Medicine. He joined the Johns Hopkins faculty in 2017.
