My primary research interests are in the areas of Natural Language Processing, Machine Learning, and Computational Social Sciences.
Before moving to the gorgeous Pacific Northwest, I was a Postdoctoral Researcher in the Data Mining lab at the Department of Electrical Engineering and Computer Science, York University, Canada, where I also obtained my Ph.D. and MSc. in Computer Science under the supervision of Aijun An.
Prospective Students: I’m always looking for motivated and hard-working students who want to pursue a Ph.D. degree to join our NLP Group. Please follow the department admission guidelines to apply.
We’re interested in exploring three broad ideas under the guiding principle of Thoughtful Technology relating to machines, humans, and their interconnection:
[2021 Fall] CS 410/510 Introduction to Natural Language Processing
[2021 Spring] CS 410/510 Adventures in NLP
[2021 Winter] CS 410/510 Introduction to Natural Language Processing
Weekly NLP seminars [Schedule]
Monthly NLP + Applied Linguistics seminars (w/ Dr. Susan Conrad)
If you’re interested in attending any of these seminars, you may subscribe to our mailing list.
