Since around 2010 I have been (on and off) area chair for NIPS and ICML, senior program chair for AAAI, publications chair for NIPS and ICML and a member of the editorial board of JMLR and JAIR. Early in 2012, I became recipient of an NSF Career Award.


I am married to (the amazing) Anne Bracy. Together we have three children, Timo, Koby and Nika.
