I like to find ways to use simple statistical measures to build big things.
I am also very much interested in how Bayesian inference can be used to analyze human behavior. My favorite surrogate for behavior is some sort of sequence of symbols such as a web log, or a history of what music a person has played. The techniques I use are more general than is required for these problems and work well for analyzing human text and genetic sequences. In unpublished work, they have been very useful in authorship detection.
