Career Statement

Dr. Anindita Dey is working as an assistant professor of geology at the University of Delhi. Her academic foundation was laid at Jadavpur University, where she completed her B.Sc. in Geological Sciences and M.Sc. in Applied Geology, securing top ranks in both programs. She received the prestigious Dr. Shyama Prasad Mukherjee (SPM) fellowship for securing the first position in all-India CSIR-NET. Her passion for metamorphic petrology culminated in a Ph.D. from Jadavpur University, focusing on the petrology and geochronology of a Proterozoic poly-metamorphosed high-grade terrane in India. Her postdoctoral experiences include the Dr. D. S. Kothari Post-doctoral Fellowship at the University of Calcutta and an RUSA Post-doctoral Project Fellowship at Jadavpur University.

Research Interest

Currently, her research endeavors revolve around the study of fluid-altered black-wall rocks within a Proterozoic shear zone. The primary aim of this work is to gain insights into the impact of fluid character and element mobility on the formation of extremely high aluminous minerals in localized domains.

Furthermore, her research interests extend to the investigation of formation and stability of minerals, along with the development of various micro-textures within rocks with the help of themodynamic modelling techniques. She made contributions to this field by enhancing our understanding of how the presence of fluorine (F) influences the thermodynamic stability of vesuvianite-garnet assemblages in calc-silicate rocks and the role of F in aluminum substitution in titanites. She has also worked on the formation of corona texture to understand the role of multiple competing factors controlling their structure.

She is deeply engaged in the study of the petro-tectonic evolution of orogenic belts and their role within different supercontinental cycles using the principles of metamorphic petrology geochemistry and geochronology. She worked on the evolution of Proterozoic polymetamorphic terranes of India to unravel their complex metamorphic and magmatic histories.
