I completed my Ph.D. at the Tata Institute of Fundamental Research, Mumbai in 2010. Currently, I am working as an Assistant Professor in Department of Physics IIT (BHU) since October 2015. My research interest mainly comprises of understanding the microscopic origin of various novel condensed matter phenomena like e.g. Kondo effect/heavy fermion behavior, unconventional superconductivity, topological order in condensed matter, quantum criticality etc. To this end, we primarily use electron spectroscopy-based techniques for investigating the electronic structure of those systems which is known to give rise to these interesting properties at the macroscopic level. Subsequently we also perform electronic structure calculations for those systems using density functional theory (DFT) in order to better understand the experimental data.

Recently we have ventured into single crystal growth of materials in parallel to the above. The single crystals successfully grown so far comprise of the topological insulator compounds like Bi2Se3, Bi2Te3 and Sb2Te3 and their derivatives etc.
