I am an assistant professor in the Department of Computer Science in the Luddy School of Informatics, Computing, and Engineering at Indiana University Indianapolis. I am also an affiliate professor in the Department of Computer Science at the University of British Columbia .

My work explores language use from a computational perspective to facilitate human communication. Using Machine Learning and Natural Language Processing (NLP) techniques, I discover patterns in text and build computational models of language use that are able to process large amounts of linguistic data. I investigate how people use language by bridging computer science and the disciplines of linguistics and psychology in the application domains such as health care and education.

I received my Ph.D. from the Language Technologies Institute at Carnegie Mellon University. After that, I was a CIHR Health System Impact Postdoctoral Fellow at the University of British Columbia and BC Centre for Disease Control.

I am seeking a highly motivated student with a strong background in ML/NLP for our Ph.D. program. If you are interested, please send me your resume, unofficial transcripts, and a brief description of your research interests.
Unfortunately, due to a large number of requests, I won’t be able to give individual feedback.
