The focus is on Magnetotelluric investigations, which have greatly advanced understanding of lithospheric and crustal structures across diverse geological settings. With a solid background in this area, I contributed to research on electrical resistivity patterns in regions such as the Kaladgi/Cambay/Vindhyan rift Basins, the Dharwar Craton, geothermal zones (Puga and Chumathang) in the Leh Ladakh NW Himalaya, and the electrical structure of the Sikkim Himalaya. Magnetotelluric studies have been instrumental in revealing the deep tectonic framework and crust-mantle interactions in complex terrains. By applying Magnetotelluric techniques, I have published findings widely in prominent international journals, reflecting extensive expertise in analysis and interpretation.
