About

I am an Assistant Professor at the School of Computing at George Mason University and currently a Visiting Assistant Professor at the Department of Computer Science at Duke University.

My research interests are in Computational Linguistics and Natural Language Processing. Drawing on variational and applied linguistics, I investigate language variation at both systemic and individual levels and develop computational methods to improve the safety, robustness, and accessibility of NLP systems in the age of LLMs.

I am Program Chair for SemEval (2025–2026) and co-organizer of the VarDial workshop since 2024. I have served as Tutorial Chair for ACL 2022 and Faculty Advisor for NAACL SRW 2024, alongside regular area chair and senior area chair roles at all major NLP venues.
