Postdoc Researcher

I am Vasudha Varadarajan, a postdoc researcher at CMU’s Language Technologies Institute working on understanding how social cognition surfaces in large language models, its impact on conversations and cultural sensitivity , and the safety risks associated with it, especially in downstream applications such as mental health. I am also interested in using insights from NLP and data science techniques (what we call “neo-GOFAI” - modern applications of good old-fashioned AI and statistical techniques) to study social / psychological phenomena. I am also interested in interpretability and explainability of language models, and exploring NLP for low-resource and code-mixed settings. I did my PhD under the mentorship of H. Andrew Schwartz in the State University of New York at Stony Brook. I am fortunate to be mentored by Maarten Sap and Mona Diab at LTI.

Teaching and Mentoring

High School Research Mentorship

I mentored a high-school student from NJ on “Language of Neurodegenerative Patients and their Caregivers on Social Media”. They have been inducted into American Junior Academy of Sciences (AJAS) and invited to present their work at American Association for the Advancement of Science (AAAS) annual meeting in 2026.

Research Mentorship

Mentorship of junior students has led to some papers under review at *CL venues.

1000 Girls, 1000 Futures

Virtual mentoring by the New York Academy of Sciences’ Global STEM Alliance.
