Bio

I am a Computer Science Ph.D. student in the School of Interactive Computing at Georgia Tech. I work in the Social Dynamics and Wellbeing Lab, and I am advised by Dr. Munmun De Choudhury. I did my undergraduate in Computer Science and Engineering from IIT Kharagpur, and hold an overall industry research experience of five years.

I am interested in the interdisciplinary area of computational social science to study individual and collective wellbeing using social media. By complementing multimodal datastreams with social media, I adopt methods from machine learning, statistics, natural language, and causal inference analysis to sense, predict, and examine psychosocial wellbeing and dynamics of individuals and collectives, particularly those in situated contexts, such as college campuses and workplaces.
