I am a theoretical condensed matter physicist by training who enjoys working in diverse areas of physics. A few of my research interests include quantum many-body theory, physics of disordered systems, quantum computation, transport, and topological phases. Additionally, I enjoy examining interdisciplinary topics related (but not limited) to statistical physics, optics and machine learning.

Educational Background:

  • Integrated Bachelors-Masters degree (2011); Indian Institute of Science Education and Research, Kolkata (IISER-K)
  • Ph.D. (2019) in Physical Sciences, Indian Institute of Science (IISc), Bangalore

Research Interests:

  • Quantum many body systems and phase transitions pertaining to exotic phases like superconductivity, Mott insulators, and non-Fermi liquids.
  • Developing numerical/analytical techniques for studying strongly-correlated physics
  • Understanding and exploring non-equilibrium physics and thermalization in interacting systems.

  • Exploring topological phases and their classification. Application of topological phases in quantum computation. Realizing topological phases on various quantum and classical platforms.
  • Using quantum theory to understand nano-scale systems and design new devices.
  • Exploring light-matter interactions. Application of light-matter interaction to optical trapping, measurements, and computation.
  • Developing open-source software targeted towards research.

















Professional Experience:

  • Postdoc, Indian Institute of Science (IISc) (Feb 2019 - Aug 2019).
  • Postdoc, University of Toronto (Sep 2019 - Aug 2022).
