About
Research Area

I am an igneous petrologist and I use outcrop features, petrography and mineral-chemical to geochemical data (including radiogenic isotopes) to understand the nature of magmas and their evolution in space and time. I have special research interest for structural and textural evolution of magmas/lavas during their emplacement and cooling. My present field of research include Alkaline Magmatism in Precambrian Terrains, Silicic to Mafic Volcanism/Plutonism in Continental Flood Basalt Provinces and Ophiolites in Subduction/Collision Zones.
