Brief Profile

Having experience in the analysis of pesticide residues in agricultural food produce and human biological samples. Expertise in field demonstrations to the local farming community on the GAPs/GHPs through extensive education and training programs and through intervention studies to minimize the exposure to pesticides. Developing strategies to minimize the pesticide residues in the selected food produce at house hold levels by way of ideal household methods of processing at the community level. Developing cost-effective, re-usable personal protective equipment at the field level. As part of extension activities, extensive education and training programmes through video films in three (local Rregional/Hindi/English) were also developed so as the information to be reaching and reinforcing to the community and thereby to sustain the program on a continuous basis.
