"The dog scratched and scratched but it was no use."
About MeI am an associate professor in the Computer Science Department of Columbia University, where I do research in theoretical computer science. My main research interests lie in computational complexity theory, computational learning theory, property testing, and the role of randomness in computation.
Some Current and Recent TeachingFall 2015: COMS 4252: Introduction to Computational Learning Theory
Spring 2014: COMS 6998: Sublinear Time Algorithms in Learning and Property Testing

A Very Brief And Dry BiographyBefore coming to Columbia I was an NSF Mathematical Sciences postdoc in the Division of Engineering and Applied Sciences at Harvard University. I received my Ph.D in computer science, my MS in computer science, and my AB in Mathematics all from Harvard.

"I'll tell you what you can do," he said. "You can find the coffee pot you used last time you made coffee and maybe there's some grounds left over in the ground holder and you can give me a paper napkin and I can saturate the napkin with soggy coffee grounds and just hold it under my nose and sniff it for a little while."
