I'm currently a Research Scientist at Snapchat.

After defending my PhD thesis in Carnegie Mellon working under the ingenious William W. Cohen, I worked at Microsoft (Bing and Live Labs), Qualcomm Research, and Inome. In a previous life I also worked as a software engineer at Ericsson on real-time call allocation and other cell phone networks related problems. I'm interested in applied research interfacing Machine Learning, Information Retrieval and Text & Data Mining. In particular, I have worked on text mining, learning specific ranking functions for web search, long web query retrieval, sampling techniques for large scale evaluation, information extraction, classification and user recommendation models for email (speech acts, email leaks, recipient recommendation, etc.), and a handful of other interesting topics.
