Hello, I am an Assistant Professor in the Department of Computer Science & Engineering at Washington University in St. Louis. I received my Ph.D. from UPenn in Machine Learning under the supervision of Lawrence Saul. I did my undergraduate degree in Mathematics and Computer Science at the University of Oxford.
My main line of research is in and around Machine Learning. In particular, I focus on high dimensional data analysis, machine learned web-search ranking, metric learning, multitask- and transfer-learning settings and, brain decoding. Currently, my lab has developed a special focus on test-time cost-sensitive learning. 
In 2012 I am area chair for NIPS and ICML, senior program chair for AAAI, publications chair for ICML and a member of the editorial board of JMLR.
Early this year, I was recipient of an NSF Career Award.
I am married to (the amazing) Anne Bracy. Together we have two sons, Timo and Koby.
If you are an undergraduate student, interested in summer research, please consider the WashU REU program.
