I am a nutritionist with research interests focusing on the intersection between agriculture/food systems, gender relations, and nutrition. My expertise spans methods and metrics in agriculture-nutrition research, program design, operations research and theory-based policy and program impact evaluation to inform policy investments for improved nutrition outcomes. In addition to the classic experimental and quasi-experimental methodologies, my scientific inquiry also draws from econometric methodologies and mixed methods.

II am the principal investigator of IMMANA (Innovative Methods and Metrics for Agriculture and Nutrition Actions), a FCDO-BMGF funded partnership to stimulate the development and application of scientifically sound methods and metrics in agriculture, health and nutrition research. IMMANA includes the Agriculture, Nutrition and Health (ANH) Academy, a global network of over 9000 researchers and practitioners from 145+ countries working at the nexus of food systems, nutrition and health.


I am the co- principal investigator on Indian Food Systems for Improved Nutrition (INFUSION). INFUSION seeks to improve understanding of the functioning of rural food markets from a nutrition perspective. It is establishing, testing and delivering evidence for market interventions that improve the availability and affordability of nutrient-dense foods (especially fruits, vegetables and animal-sourced foods) in rural communities in Bihar and Odisha in India.

I was the principal investigator of UPAVAN (Upscaling Participatory Action and Videos for Agriculture and Nutrition), a four-arm cluster RCT integrating maternal and child nutrition objectives into a participatory low-cost video-driven agriculture extension platform in Odisha, India. I also the co-principal investigator of a large-scale program impact evaluation of a video-based maternal and child nutrition behaviour change communications programme, SAMVAD, in 5 Indian states using an innovative evaluation methodology.

I was a co-investigator of MINI (Market Interventions for Nutritional Improvement), a system dynamics modelling study examining the potential for market-based interventions to improve availability of fruits and vegetables in nutritionally vulnerable areas in Bihar, India.

I co-lead the food systems theme of the UKRI GCRF Action Against Stunting Hub
