About

I am a postdoctoral researcher at the Istituto Italiano di Tecnologia working at the 'Graphene Labs', Genova in the research division 'Theory and technology of 2D materials' with Prof. Marco Polini. I am currently employed in this position since 2019. Before that, I was a postdoc in the Institute of Theoretical Physics, TU Dresden in Prof. Carsten Timm's group from 2017. I completed my doctoral studies in 2017 at the Indian Institute of Technology Kanpur (supervisor: Prof. Avinash Singh) working on electronic structure and antiferromagnetism in Fe-pnictides. 

My research interests cover a wide range of topics in the broad area of Condensed Matter Physics including strongly correlated systems, topological materials, quantum magnetism, strongly spin-orbit coupled systems. My long-term exposure to working on these topics has equipped me with the necessary skills of utilizing a large variety of condensed matter techniques including tight-binding methods, calculations of linear responses, perturbative calculations like random phase approximations, etc. I am familiar with a series of many-body tools like Green’s function, Spin-Fluctuation Approach, Diagrammatic Techniques, Quantum Transport, Exact Diagonalization, classical Monte Carlo methods, along with the scientific programming language FORTRAN, PYTHON.
