I work as a research assistant professor in the department of Neurology at the University of Pennsylvania. This is a grant-supported, non-teaching faculty position. I used to spend most of my time on my own research, now I spend most of my time developing software for functional neuroimaging data analysis. I received my AB in cognitive studies from Princeton in 1989, and my PhD in cognitive psychology from Carnegie Mellon in 1994. For more of my professional (academic) background, see my research page or write to request my Curriculum Vitae.

I've written a book on poker, titled "Serious Poker," and from 2001-2006 I wrote a regular column for Card Player Magazine, called "Thinking About Poker." I have a non-commercial poker web site at seriouspoker.com, although since poker got popular, I haven't maintained it. I don't play poker professionally.

I live with my wife, daughter, and miniature schnauzer in a quiet suburb just West of Philadelphia. I was born in Center City Philadelphia, and I'm loyal to the local teams, even though they don't care much about me.
