Payal is a third year Ph.D. student in the field of Applied Economics and Management. Her work is primarily focused on development economics and applied econometrics. As a TCI Scholar, her fieldwork focuses on linkages between sanitation and nutrition. Working with the partner NGO Grameen Development Services, Payal will examine the behavior change methodology known as Community-led Total Sanitation which stimulates a collective sense of disgust and shame among community members as they confront the crude facts about mass open defecation practices and its negative impacts on the entire community. She desires to analyze the bearing of this behavior change along with construction of toilets on the sanitation practices, diarrheal incidence in children and the safety of women.
