Currently I am working as CSIR-Research Associate at CSIR-National Geophysical Research Institute. I received my B.Sc.(H) in Geological Science and M.Sc. in Applied Geology from Jadavpur University, Kolkata, India. I received my Ph.D. from the Indian Institute of Technology Kharagpur, India.
My research focuses on understanding the Precambrian geodynamics and crust-mantle evolution utilizing major trace elements and lanthanides (REEs). Apart from constraining the mechanisms using inorganic geochemistry, I use plasma and thermal mass spectrometry to assess the isotopic compositions of primary, secondary, and tertiary crust using Rb-Sr, Sm-Nd, and Lu-Hf systematics by the Isotope Dilution Mass Spectrometry (IDMS) technique. We can better understand the processes involved in magma extraction from the mantle and crystallization at shallow to deep crustal levels through geochemical studies and the timing of these events by using data from these mass spectrometers. Geochemical and radiogenic isotopic studies of terrestrial samples from Archean cratons provide insights into the ancient geological processes and timing of greenstone volcanism and the emplacement of dyke swarms. Consequently, deciphering the petrogenesis and tectonic settings of supracrustal greenstone belt meta-volcanics (Iron Ore Group of rocks) and intra-cratonic dykes within the Singhbhum craton, India.
