His research interest is Precambrian crustal evolution. He uses geological mapping, elemental and Nd isotope geochemistry, and zircon U-Pb dating and Hf isotope (including detrital zircon) study on Archaean granite-greenstone belts of Dharwar and Singhbhum cratons of India. His research aims to unravel events of juvenile crustal addition and crustal reworking, their global significance, nature of crust-mantle interaction and tectonics of the early Earth. He is also interested in tectonics of the vast Proterozoic platform basins of India and contemporaneous surface processes. He has published in journals like Gondwana Research, Precambrian Research, Geological Society London Memoir and Special Publications, Journal of Asian Earth Sciences, Acta Geologica Sinica, and Journal and Memoir of the Geological Society of India.
