About Me

I'm a fifth-year PhD candidate in the Operations Research Center at MIT, with an expected graduation in Spring 2018. I am advised by Juan Pablo Vielma and was previously supported by the NSF Graduate Research Fellowship. I received my B.A. in Applied Mathematics from Rice University, where I worked with Beatrice Riviere and Hadley Wickham. I've also spent time at Akamai Technologies, Argonne National Laboratory, and Lawrence Berkeley National Laboratory.

Research Interests

My primary interests are in the use of mathematical optimization to solve difficult decision problems. Much of my current work is in the area of integer optimization. I am also interested in computational technology, and particularly user-facing software tools for modeling and decision-making.
