Overview

I am interested in applying science knowledge to meeting global needs in agriculture and the environment. I tend to take a big picture approach that is based on science knowledge.

Research Focus

My research concentrates on three areas: agriculture, the environment and human health. I am increasingly interested in linking agriculture to human nutrition and health in the international context and energy production in the domestic context. My work in the agriculture and nutrition area is done through projects on the rice-wheat rotation in S. Asia, food chain aspects of arsenic contamination in Bangladesh and production of ringspot resistant transgenic papaya for S. Asia and E. Africa. My work on agriculture and energy is aimed at development and adoption of renewable biofuels in the USA, with concomitant mitigation of greenhouse gas emissions. I maintain a long-term interest on the functions and dynamics of soil organic matter, nitrogen cycle processes in upland and flooded soils, and on various aspects of agricultural impacts on greenhouse gas fluxes and climate change. My objectives are to contribute to (1) improving agriculture and natural resource management, especially in developing countries, and (2) broadening the paradigm of agriculture from a focus on productivity and profitability to include nutrition and health outcomes and sustainable use of resources.

Outreach and Extension Focus

(1) Biofuels and carbon sequestration in soils: (2)Enhancing technology adoption in rice-wheat cropping systems of S. Asia.

Instruction Focus

(1) Organic matter in soils, sediments and water: (2) Plant mineral nutrition
