My primary research interest lies in applying trace elements, major elements and isotopes in studying Earth processes. Specifically, these include
  • Petrology and geochemistry of igneous and metamorphic rocks
  • Applications of Sm-Nd, Rb-Sr, 40Ar/39Ar and U-Pb systematics in geochronology and thermochronology
  • Isotope geochemistry and geochronology in studies of crust-mantle evolution and petrogenesis
  • Ground water and river water geochemistry and the marine Sr and Os isotopic record
  • Continental flood basalt geochemistry and geochronology and mantle plume volcanism
  • Mineralogy, petrology and geochemistry of impact craters and meteorites
  • Impact tracers at geological boundaries and mass extinction
  • Petrology and geochemistry of subduction-zone metamorphic rocks, mantle-wedge processes and tectonics
  • Archean geochronology, crustal evolution and sedimentary Fe-Mn ore deposition
We have used the above geochemical tools to study a wide variety of topics in earth sciences such as: Archean crustal evolution; meteorite impact origin of the Sudbury Complex, the P-T impact evidence from the discovery of chondritic meteorite fragments at the Graphite Peak, Antarctica; Mesozoic mantle plume volcanism; Tertiary arc-trench collision evidence, understanding volatile and mass transfer mechanisms in the mantle wedge; arsenic release mechanism in the Bengal Basin groundwater, submarine groundwater discharge and the marine Sr-isotopic record, Himalayan foreland basin weathering; and others.
