I earned my bachelor’s degree in physics from Williams College, worked briefly for A9.com and IMVU, and spent a few years in an economics Ph.D. program at the University of Chicago. Academia wasn’t for me, so now I make a living developing software and mathematical tools. You’ll find my ranking algorithms in use at some of the largest destinations on the Internet, and my statistics software cited in top medical journals. Need consulting or speaking? Email me.
