Hello, and welcome to my personal website. I am an Assistant Professor of Management Science at the University of Miami. I received my PhD in Operations Management from Stern School of business at New York University, and my BSc in Mathematics from the University of Athens. My research focuses on designing and optimizing service operations, with an emphasis on healthcare delivery. Broader areas of interest include Stochastic Modeling, Applied Probability, Scheduling, Simulation, Optimization.
