  • Assistant Professor at the Department of Geology, Central University of South Bihar (August 2022- Present).
  • Institute Post-Doctoral Fellow at the Department of Earth Sciences, IIT Bombay (October 2021- August 2022).
  • My research aims to use minerals as tools in the field of mineralogy, sedimentology and geochronology/thermochronology to solve and understand various geological problems. The thrust research areas in which I am working are source-to-sink linkage, sediment provenance study, paleo-drainage reconstruction and landscape evolution. I studied the provenance of Assam-Arakan Basin fluvial sedimentary units by integrating petrography, heavy mineral analysis, EPMA analysis for dense mineral chemistry and detrital zircon U-Pb dating. This sediment-source investigation showed the importance of provenance study in reconstructing the paleo-drainage evolution of the Brahmaputra River in the northeast Himalayas. Moreover, I also worked on low-temperature thermochronological studies (Apatite Fission Track dating) to determine the exhumation history of the Shillong Plateau.
