I grew up in different states of India (Darbhanga, Bihar, from 1993 until 1999, Delhi from 1999 until 2001, and Sonipat, Haryana, from 2001 until 2007) and studied for my Bachelors degree in Physics at <ahref="https://www.ststephens.edu">St. Stephen's College, Delhi</a> while being a KVPY (highly competitive programme funded by the Department of Science and Technology of the Government of India) scholar. In 2010, I received a one-year Erasmus scholarship from the European Union to study for an MS at the University of Paris (now Sorbonne University). I did my Masters thesis research on trilayer graphene using ab-initio density functional theory calculations using Quantum ESPRESSO. I then moved back to India and completed another Masters in Astroparticle Physics from Bose Institute and St. Xavier's College (2011-2013) and wrote my MSc thesis research on Monte Carlo methods for path integral approach to quantum field theories (QFTs). The Government of India awarded me the CSIR/UGC fellowship in my final year of MSc which I had to decline since I moved to the US.

In 2013, I joined the physics department at Syracuse University and obtained my PhD in 2019 on aspects of holography, large N, and lattice supersymmetry. Later that year, I moved to Waterloo, Canada, for my first postdoc and returned to the US for my second postdoc in 2022.
FOR STUDENTS: If you'd like to work on a research project with me, please contact me. Unfortunately, until I get a permanent position, I cannot write a reference letter for your future applications. If you agree and are interested, I'd love to talk. In my research, I consider various problems related to lattice gauge theory, tensor networks, qubits and qumodes in quantum computing, matrix models, computational complexity theory, variational algorithms like conventional VQE and d-sparse VQE, Hamiltonian simulation, and scrambling in randomly coupled systems.

FOR STUDENTS: If you'd like to work on a research project, please contact me. Until I get a position, I cannot write a reference letter for your future applications. If you are still interested, I'd love to talk and discuss potential projects. In my research, I am broadly interested in various problems related to lattice gauge theory, tensor networks, qubits and qumodes approach to quantum computing, matrix models, computational complexity theory, variational algorithms like conventional VQE and d-sparse VQE, Hamiltonian simulation, and quantum chaos in random systems.

My research interests cover several exciting areas of theoretical physics. At the start of my Ph.D., I focused exclusively on supersymmetric gauge theories as non-perturbative formulations of string theory through gauge/gravity duality. In this field, I'm most interested in studying finite-temperature maximally supersymmetric gauge theories using Monte Carlo (MC) methods to test and understand non-extremal black p-branes in dual supergravity (SUGRA). This numerical approach provides a tool for potential non-trivial checks of the AdS/CFT conjecture.
