I am currently working as a Post-Doctoral Associate in the Department of Physics and Astronomy at Rutgers University. Before this, I worked as a Postdoctoral Research Associate in the Physics of Condensed Matter and Complex Systems Group (T4), Theoretical Division, Los Alamos National Laboratory

Prior to this, I received my PhD from the University of Tennessee, Knoxville under the supervision of Prof. Johnston. My Ph.D. thesis, titled 'Study of spin and charge dynamics in one-dimensional (1D) cuprates using resonant inelastic x-ray scattering (RIXS)' focused on developing theory and models for RIXS spectroscopy relevant for 1D correlated materials. Previously, I got my Bachelors degree in Engineering Physics from IIT Delhi.

I am interested in studying strongly correlated electrons using numerical techniques. My focus primarily lies in using low-dimensional spin chain systems and Hubbard models to study quantum spin liquids and superconductivity. 

I am currently editing a research topic titled "Exploring strongly correlated materials using resonant inelastic x-ray scattering" for Frontiers Media. Please contact me if you are interested in contributing to the topic.
