Before coming to New York, he was a Research Fellow in the Machine Learning Group of
Zoubin Ghahramani at the University of Cambridge, and previously a graduate student of Joachim M. Buhmann at
ETH Zurich. His main research interests are the statistics of discrete objects and structures: permutations, graphs, partitions, and binary sequences. Most of his recent work concerns representation problems and latent variable algorithms in Bayesian nonparametrics. More generally, he is interested in all mathematical aspects of machine learning and artificial intelligence.
