I'm an Assistant Professor in the Department of Computer Science at Georgetown University. I obtained my Ph.D. in Computer Science from Carnegie Mellon University. Before that, I studied at the National University of Singapore.
My research interests lie in Information Retrieval, Text Mining, Natural Language Processing, and Machine Learning.
I am looking for highly-motivated PhD students with strong mathematic background, excellent programming skills, and good writing skills. If you are serious about Information Retrieval research and/or aim to invent the next big thing on the Web, please contact me .
