I am a PhD candidate in Language Technologies Institute, School of Computer Science at Carnegie Mellon University. My advisor is professor William W. Cohen. My research interests are Machine Learning, Information Retrieval, and Natural Language Processing.

I am generally interested in models with rich structures, and am currently studying relational models for information retrieval and extraction applications. Previously I have studied a wide range of topics such as robotic soccer, computer system diagnosis, product search, and question answering.

My CV, research statement, and thesis proposal

Fun with math and programming.
