My research brings together transdisciplinary systems thinking approaches and methods to understand complex social-ecological systems.

CURRENT PROJECTS

Indigenous (Adivasi) Foodways for Sustainable Food Futures

Tufts Springboard grant (2024-2026)

This project brings together an interdisciplinary team across systems science, anthropology, nutrition, and agroecology in partnership with indigenous communities in Eastern India to i) trace the co-evolution of Adivasi food systems with political, economic, and ecological changes over time; ii) develop an integrated framework for understanding foodways bridging indigenous research, systems science, and anthropological perspectives; and iii) foreground indigenous perspectives into food systems discourse and pathways towards sustainable food futures.

Modelling Pathways for Climate-Food-Nutrition-Health Nexus for Human and Planetary Health

ICNSM seed grant (2025-2026)

This project represents the second phase of the Adivasi Foodways research, expanding the work to include Particularly Vulnerable Tribal Groups (PVTGs) in Karnataka and connecting insights from the earlier foodways research to broader questions of climate, food, nutrition, health, and policy in India.

Building on a place-based understanding of Indigenous food practices, knowledge, and social-ecological change, this phase examines how climate and environmental change affect health through interconnected food and nutrition pathways. It also explores how agricultural, food, nutrition, and social protection policies intersect with these pathways and shape household choices, vulnerabilities, and opportunities for adaptation.

The project combines community-grounded data and knowledge with GIS-based climate analysis and system dynamics modelling to connect lived experiences with broader climatic and policy dynamics. Through this integration, we aim to identify locally grounded and policy-relevant pathways toward climate resilience, food and nutrition security, and human and planetary health.

A Growing Vision

My vision is to expand this work across Indigenous communities in South and Southeast Asia, exploring the connections among food and biodiversity, Indigenous knowledge and economies, human health and well-being, and climate resilience. Through comparative, community-grounded research, I hope to understand how diverse foods, landscapes, livelihoods, and ways of knowing can contribute to healthier, more equitable, and resilient pathways for people and the environments they inhabit.

If you are interested in contributing to this work, sharing knowledge, or exploring opportunities for collaboration, please get in touch. I welcome connections with Indigenous communities and knowledge holders, researchers, practitioners, artists, and organizations working toward similar goals.
