I am a 5th year Ph.D. candidate in the Department of Electrical and Computer Engineering at the University of Maryland. I am a member of the Language and Media Processing Laboratory (LAMP) and the Institute of Advanced Computer Studies (UMIACS). My advisors are Dr. Rama Chellappa and Dr. David Doermann. I am working this summer at the Yahoo! Search Group.

My research interests include computer vision and machine learning, and their application in the processing and retrieval of visual content involving heterogeneous and un-structured data.
