He studies and evaluates the meanings behind the design, construction and implementation of different health, nutrition and other communication campaigns specifically in vulnerable and marginalized communities. His research investigates and analyzes the lack of community voices, lack of community participation and the absence of cultural and contextual understandings in the myriad communication interventions that result in marginalization, vulnerabilities and creation of health disparities and inequities. Dr. Acharya's research uses cultural frameworks like the Culture Centered Approach (CCA), PEN-3, social theories like Social Suffering, Structural Violence, Unintended consequences of purposive action and other social and psychological hypotheses.
