I am a Principal Researcher at Microsoft Research. I am interested in data and signal analysis problems that reduce complexity and remove pain points for users. My current interests include economics, authentication, safety and data-driven security. There are links to some papers and projects below.
Here's a short profile of me done by MSR. Some media coverage of my work: All Things Considered (NPR), the Boston Globe, the NY Times, Wired, Ars Technica, theAtlantic, Bloomberg TV, The Economist, the Wall St Journal.
