I was an assistant professor in the mathematics department at Brandeis from 2001 to 2004. I then worked at the Broad Institute at MIT, on mathematical and computational problems associated with whole genome assembly, and at BBN Technologies, on problems in machine learning for speech recognition. I now work at Google.
Before coming to Brandeis, I was an NSF post-doc at MIT, hosted by Richard Stanley. I received my Ph.D. at U.C. Berkeley in 1998 under the direction of Nicolai Reshetikhin (my family tree, thanks to the MGP).
Papers and cv
On the lighter side, here is a crossword
puzzle I wrote, which appeared in the Mathematical Intelligencer
(25#1, Winter '03). Recommended for mathematicians only.
Here is a second one, Weirdoes,
which appeared in MI 27#3, Summer 2005. More accessible,
not as good.
Update 7/14/2007: I no longer hold the world's record for longest known game of "Beggar Your Neighbor". Richard Mann and Nick Wu ("The Beggar-Your-Neighbour Research Group, Oxford, UK") have found a 975-trick game:
