About

I am currently a PhD candidate at Math and Computer Science Department of Emory University. My interests include Information Retrieval, Human Computer Interaction, Machine Learning, and Health Informatics. My advisor is Dr. E. Agichtein.

Before coming to Emory I received my M.S. degree in engineering from Moscow Institute of Electronic Technology (MIET) in 2008.
