My interests are in various applied problems which have impact. My formal training is in electrical engineering and applied mathematics. I find that some of the more interesting problems I have worked on have come from looking at the real world with a strongly quantitative toolset. Along the way, I have spent time at a hedge fund and consulted for private industry and the U.S. Government.

I’ve also started to keep track of where the grad students who have worked with me do internships:

Most of my current research involves looking at data from a quantitative perspective and with a socially-important goal. If you are interested in working with me, be prepared for getting your hands dirty. Further thoughts about projects and letters of recommendation.
