I am an Associate Professor in the Department of Statistics at Columbia University. Before coming to New York, I 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.
My main research interest are the statistics of discrete objects and structures: permutations, graphs, partitions, binary sequences. Most of my recent work concerns representation problems and latent variable algorithms in Bayesian nonparametrics. More generally, I am interested in all mathematical aspects of machine learning and artificial intelligence.
