Koustuv Saha

About Me

I am a Computer Science Ph.D. candidate 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 areas of computational social science and social computing. 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 wellbeing and psychosocial dynamics of individuals and collectives, particularly in situated contexts, such as college campuses and workplaces.
