I study operations research, specifically the theory and application of optimization. Much of my current work is concerned with mathematical formulations: that is, how to translate a high-level optimization problem to a mathematical description we can solve efficiently.
I'm also interested in all aspects of computational optimization, especially user-facing tools for modeling and for developing advanced algorithms.
I'm a PhD student in the Operations Research Center at MIT, advised by Juan Pablo Vielma. I'm supported by the NSF Graduate Fellowship. I received my B.A. in Applied Mathematics from Rice University, where I worked with Beatrice Riviere and Hadley Wickham.
