Welcome.
I am Associate Professor in the Department of Statistics at Columbia University. I study symmetry principles, Bayesian nonparametrics, network and relational data, and hierarchies of latent variables. More generally, I am interested in all mathematical aspects of machine learning and artifical intelligence.
I was an undergraduate at the University of Bonn, a PhD student of Joachim M. Buhmann at ETH Zurich, and a postdoc of Zoubin Ghahramani at the University of Cambridge.
