Previous research was with CG centers working with national programs in South Asia on improving the productivity of rice-wheat cropping systems. It promoted participatory and on-farm research approaches, integrated crop management, weed science, IPM, nutrient management, machinery development, zero-tillage, and all aspects of crop production in local farming systems.

International and Tropical cropping systems, agroforestry, conervation agriculture and soil health, machinery and the use of transgenic crops in modern agriculture.

I have some links with the Cornell NYS Soil Health initiative, but most of my extension and outreach was done internationally in South Asia with CIMMYT and IRRI working to extend improved and sustainable crop management recommendations to local farmers with national scientists and extension workers.
