About me

I'm a doctoral candidate in Computer Science at the School of Interactive Computing at Georgia Tech. I work in the Social Dynamics and Wellbeing lab and am advised by Munmun De Choudhury. Previously, I was at International Institute of Information Technology Hyderabad, India where I completed my undergraduate and graduate studies in Computer Science with a research specialization in Humanities.

I am broadly interested in Computational Social Science, wherein I apply methods from statistical modeling, machine learning, and natural language processing to study human behavior as manifested on online social systems and derive insights specific to health and wellbeing. My research examines how social media supports clinical and social pathways to care for mental health. Along this exploration, I care deeply about the validity (or invalidity) of online measurements of behavior and the implications of research to all stakeholders involved.
