Research

My main areas of interest are general relativity, field theory and black holes. Over the past few years my research has been directed towards following topics:

  • Near horizon symmetries of black holes
  • Gravitational Memory Effect
  • Classical & quantum instabilities inside the black holes
  • Quasi normal modes of black holes
  • Black hole thermodynamics
  • Statistical mechanics & linear response theory.
  • Non linear dynamics and infectious disease modelling.
