Senior Scientist at Microsoft Bing

I defended my PhD thesis in Carnegie Mellon in the Summer 2008, working under William Cohen. Currently I'm a senior scientist at Microsoft Bing. Before that, I was a scientist at Microsoft Live Labs.

I'm interested in applied research interfacing Machine Learning and Information Retrieval. In particular, I have worked on learning ranking functions, text mining, information extraction, classification models (stacked, online, collective, etc.), user recommendation models for email (speech acts, email leaks, recipient recommendation, etc.), and a handful of other interesting topics. More recently, I've been working on metrics, sampling, and learning techniques for "real-time" web search.
