Since July 2009 I work for Two Sigma, a medium-sized financial company in New York City. I'm having a lot of fun there designing reliable software.
I have a Ph.D. in Software Engineering from Carnegie Mellon University's School of Computer Science. I graduated in May 2009 with my thesis on API protocol compliance in object-oriented software. My advisor is Jonathan Aldrich. I hold a M.S. degree from Carnegie Mellon and a B.S. degree from Hasso-Plattner-Institute, Potsdam, Germany.
