I pursued my Ph.D. from the Department of Geology, University of Calcutta, India. By training, I am a structural geologist and a modeller. During my Ph.D., I tried to understand the progressive changes in the deformation behavior of the Himalayan wedge material from the hinterland to the foreland. Field studies, microstructural analysis from natural rocks, and experiments (numerical and analogue) are the three major components of my thesis. 

However, during my postdoc, I tried to expand my horizon and achieved expertise in High-P-T rock deformation, sintering very fine-grained polycrystalline aggregates, and microstructural characterization. I am interested to understand the rheology of different geomaterials and the processes associated with strain localization from grain-scale (μm) to plate-scale (km). Fundamentally, I try to connect the rheological creep laws to grain-scale rate-limiting deformation mechanisms of different minerals. 

I finished my first postdoc at the Earthquake Research Institute (ERI), University of Tokyo in January, 2020. Here, I focused on the clinopyroxene (diopside) diffusion creep rheology at the lower crust to upper mantle conditions. Next, I worked on understanding the rheology of the coarse-grained wet-quartzite and fine-grained novaculites, using new generation hydraulically-driven GRIGGS experiments at the Institut des Sciences de la Terre d'Orléans as a postdoc. Currently, I am working at the Woods Hole Oceanographic Institution (WHOI) to explore the rheology of the oceanic crust (/ lower continental crust), specifically focusing on plagioclase and pyroxene paleo-piezometers. I will be utilizing the traditional GRIGGS apparatus present at Brown University.
