About Me
My current research interests are focused in the fields of geochemistry, isotope geology, geochronology and petrology. I am interested in understanding the Precambrian crustal evolution, geodynamic regime of crust formation and associated metallogeny using the novel in-situ mineral based elemental and isotopic compositions. I am also highly interested in new method development using laser ablation and mass spectrometry techniques. Some of major themes on which I am presently working and interested to work:
Research Interests:
• Geochronology
• Isotope Geology
• Geochemistry
• Petrology
