I am a postdoctoral researcher at the Center for Computational Learning Systems at Columbia University, working with Dr. Nizar Habash. I received my Ph.D. in Computational Linguistics from the University of Illinois at Urbana-Champaign. I was advised by Prof. Dan Roth and was a member of the Cognitive Computation Group in the Department of Computer Science.
My dissertation was on grammatical error correction, with an emphasis on correcting errors made by non-native speakers of English. In my work, I developed models that combine machine learning techniques with linguistic knowledge. The error correction system that I built together with colleagues from the Cognitive Computation Group placed first in the CoNLL-2013 Shared Task on Grammatical Error Correction, winning by a large margin over the other sixteen participating teams.
