Research interests:

 I have a general interest in the computational and theoretical study of fundamental as well as applied problems within condensed matter physics. Particularly, the quantum simulation of electron dynamics in response to strong non-adiabatic external perturbations in various contexts such as the radiation damage, non-adiabatic coupling of molecular vibrations with the substrate electrons (metal surfaces), defect dynamics, and plasmonics. I am also interested in studying matter under extreme (temperature and pressure) conditions using first principles molecular dynamics and metadynamics. More recently I have been learning how to use machine learning tools to material science problems.

Current projects include:

  • Negative differential conductivity in semiconductors from first principles
  • High pressure electride phases in metals
  • Electronic stopping power in high entropy alloys
  • Radiation damage in heavy metals
