Brief Biography

Welcome! I am a postdoctoral scholar (research associate) in the optimization theme at the Wisconsin Institute for Discovery (WID), University of Wisconsin-Madison, working with Prof. Michael C. Ferris. My primary research area is operations research. Broadly, my interest is in the development and application of mathematical models and optimization methods, particularly for problems that have a dynamic and stochastic nature. I am interested in applications in medical decision making (e.g., radiation therapy cancer treatment), agricultural management, and energy management (e.g., stochastic unit commitment).

I received my Ph.D. degree (June 2013) in the "mathematics of everything" at MIT, Department of Electrical Engineering and Computer Science (EECS), and was affiliated with the Laboratory for Information and Decision Systems (LIDS). I worked on optimizing the delivery of radiation therapy cancer treatment dynamically over time. My advisors were Prof. John N. Tsitsiklis, Prof. David Craft, and Prof. Thomas Bortfeld. I previously received my Bachelor's and Master's degrees in Electrical and Computer Engineering (ECE) from Georgia Tech.
