Background

My work is primarily on developing sustainable and integrated management practices for insect pests that infest stored products and processed commodities. I research on variety of themes that involve both fundamentals and applied facets of agricultural entomology and molecular bioscience and, rely on comprehensive knowledge base for resolving complex and practical problems. Key findings of my research are niche oriented and heavily underpinned to industry’s operational logistics. I liase between the institutes and organisations and outreach results to the doorsteps of industry and collaborate with extension professionals and agronomists in the field for maximal adoption, and practice change. As a team, we have gone over national horizons and achieved legacy in assuring food security and market access.
