Research Interests

 

My broad research interest is statistical mechanics and its application to chemical, soft matter & biology inspired physics. I have been applying equilibrium and time dependent statistical mechanics to different problems in physical chemistry, polymer physics and biology inspired physics.

Tools I use

  • Feynman's Path Integral
  • Green's Function Techniques
  • Brownian Dynamics
  • Reaction Rate Theories
  • Integral Equation Theory (PRISM)
  • Naive Mode Coupling Theory
  • Polymer Dynamics
  • Molecular Dynamics Simulation
