I am a Researcher in the Text Mining, Search and Navigation Group  at  Microsoft Research.  Before I worked at the Machine Learning Department of NEC Laboratories America (Princeton campus) with Vladimir Vapnik, and at the Max Planck Institute for Biological Cybernetics, the Empirical Inference Department headed by Bernhard Schölkopf.

My research interests are  statistic machine learning and its application to web information retrieval. Specifically, I am working on algorithms and theoretic foundations of transductive inference, spectral clustering, kernel machines, active learning, and learning with graphs, and their applications to spam detection, relevance  ranking,  query rewriting, social network analysis, trust and reputation systems, recommendation systems, and online advertising.
