Dr. Das’ research interests are intercultural communication and health communication. Her research employs a critical approach in the field of intercultural communication, and a culture-centered approach to health communication in understanding the problematics of nations, national identity, media, and health narratives in marginalized populations in the US (Appalachia) and India. The primary focus of research in intercultural communication is to analyze critically the contesting and discursive articulation of race, caste, and problematics of representation. This analysis takes into account both national and transnational contexts through media images and language usages that shape views and ideas. In terms of health communication, Dr. Das explores the specific meanings and nuances of health issues in different cultural contexts, particularly in marginalized cultures. She also studies environmental health issues in Appalachia.
