About Me: I completed a joint Ph.D. from the Indian Institute of Technology Bombay, India, and Monash University, Australia. I worked as a Postdoctoral Fellow immediately after my PhD for a couple of months and joined the Department of Applied Geophysics, IIT (ISM) Dhanbad as a visiting Assistant Professor. My research focuses on the geophysical signatures over the Proterozoic orogenic belts over India, Australia, and Antarctica and their implications for supercontinental reconstructions. I work with Airborne and ground survey potential field datasets. It is difficult to study the poly-deformed and buried metamorphic terranes with the rock exposures alone. The geophysical potential field methods allow unravelling the subsurface structural features. My work involves identifying the geological structures with distinct geophysical signatures and correlating them with their counterparts to reconstruct the Proterozoic supercontinents. I am particularly interested in India’s position during the amalgamation and breakup of the Rodinia supercontinent. I am currently associated with IIT(ISM) teaching and guiding geophysics students. Our major research interest is in exploration geophysics focusing on the identification and quantification of deep-seated mineral resources Research Areas Interested: Mineral exploration, Supercontinental reconstructions, Potential field geophysical methods, Palaeomagnetism, Crustal structure, geophysical studies over the Proterozoic terrains, Eastern Ghats Mobile Belt, East Antarctica

Research Interest: Gravity And Magnetic Methods, Proterozoic Supercontinent Reconstructions By Using Geophysical Methods, Aeromagnetic And Gravity Interpretation, Paleomagnetism, Solid Earth Geo17 , Geology From Geo17, Structural Geo17
