Working collaboratively with Cornell faculty in four colleges and with colleagues in an NGO in India, we initiated the Nilgiris Field Learning Center (NFLC).


The Tata-Cornell Agriculture and Nutrition Initiative (TCi) is a long-term research initiative focusing on the design and evaluation of innovative interventions linking agriculture, food systems, human nutrition, and poverty in India. TCi focuses on action research to 1) increase household income and local food supply through productivity growth; 2) increase micronutrient food availability through crop diversification and food fortification programs; 3) ensure intra-household equity in food access through behavior change; and 4) improve access to clean drinking water and sanitation.

It also assists graduate student dissertation research; sponsors seminars and outreach programs, including documentaries and the Rural New York Initiative; and hosts visiting scholars from throughout the world.


I work on developing communication strategies for the SRI-Rice Center at Cornell University and on implementing knowledge-sharing efforts that serve global communities involved with the system of rice intensification (SRI) and conservation agriculture (CA). Specifically, I design and manage the SRI and CA websites and associated social media, facilitate links among international, national and topical SRI networks, and develop databases and platforms for sharing research related to SRI, CA and related systems of crop intensification.

Effective waste management can turn unwanted waste products into resources and reduce disposal costs. Waste management is part of every industry, but a waste product produced by one business can be a resource to another. Residuals from animal, food and yard waste, as well as industrial and household waste, have the potential to be valuable in agriculture and horticulture production as erosion control and nutrient and carbon sources, and in energy production and other industrial processes.


The Cornell Nutrition Analysis Program (CNAL) is an integrated research, teaching and extension/service analytical facility. The laboratory currently provide analytical support (analyses and training) in support of the research programs of more than 40 faculty members in 10 different departments at Cornell University. In addition, the laboratory staff provides training for undergraduate and graduate students in soil, plant, water and environmental analyses and interpretations of results. The laboratory's research and environmental programs currently analyze about 15,000 samples annually.
