I'm Rahul

I'm a Ph.D candidate in the School of Systems and Enterprises at Stevens Institute of Technology, advised by Dr. Sang Won Bae. My research goals focuses on applying my knowledge in applied machine learning, and affective computing to solve problems in various domains, including ubiquitous computing, mental health sensing and interaction techniques.

Before commencing my Ph.D, I graduated with a Bachelors in Technology from IIIT Guwahati, with a major in Computer Science Engineering. As an undergraduate, I worked on multiple research projects under the guidance of Dr. Ferdous Ahmed Barbhuiya, and Dr. Kuntal Dey, among others.
