I am a research scientist at the Centre for Digital Health in the University of Pennsylvania. My research aims to leverage large-scale social media image and text data to model social health outcomes and psychological traits. I use machine learning, statistical analysis, natural language processing and computer vision to answer questions pertaining to health and psychology in individuals and communities.
I also work closely with the World Well Being Project at the Positive Psychology Center and am affiliated with Penn Research in Machine Learning. My work has been covered by the American Psychological Association, Canadian Broadcasting Company, US News and other venues.
Prior to this, I completed my PhD studies on modeling users personality in multimedia preferences at the School of Computer Science and Engineering in the Nanyang Technological University, Singapore. I also worked on building Deep Learning Frameworks for Facial Action Unit Recognition while interning at Panasonic R&D. I received my undergraduate degree from BITS-Pilani, India in Computer Science.
