Area of Interest: 
ARPES studies of correlated electron phenomena - heavy fermion/Kondo phenonmenon, superconductors, semiconductors

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.
