I am a graduate student in the Laboratory for Information and Decision Systems (LIDS) at the Massachusetts Institute of Technology, supervised by Professor John N. Tsitsiklis. I graduated from the University of Illinois at Urbana-Champaign in May 2009 with a B.S. in Electrical Engineering (ECE).

Research interests: analysis, design, and decision making in large-scale stochastic systems, and applications drawn from engineering, operations, and management.

For the 2012 - 2013 academic year, I am a graduate representative on the MIT Council on Educational Technology (MITCET), and the Institute-Wide Task Force on the Future of MIT Education. Earlier, I served as co-Chair of the 2010 MIT Graduate Orientation during 2010 - 2011, a legislative advocate in the MIT Graduate Student Legislative Action Subcommittee during 2010 - 2011, and a graduate representative on the MIT Corporation Joint Advisory Committee on Institute-Wide Affairs (CJAC) during 2011 - 2012.

I enjoy rock climbing, and was a member of the MIT Ballroom Dance Team (MITBDT), where I competed in the international Latin style.
