I am an assistant professor in the department of Computer Science at UCLA. My research goal is to build intelligence systems that solve real-world problems by automatically acquiring knowledge. This challenging goal involves two fundamental components: A machine learning component that can efficiently make coherent decisions for problems with complex structures, and a natural language understanding component that enables the system to extract knowledge from unstructured text. I have been published broadly in machine learning, natural language processing, artificial intelligence, and data mining.

Please read my Research Statement to learn my general research directions.
If you are an undergraduate/master student at UCLA, please read 1~2 of my papers and drop by my office hour. Due to the large number of inquiries from prospective students, please understand that I generally cannot respond personally. But if you are a strong candidate, I will contact you during the admission season.
