Before joining LUMS Physics Department Dr. Rafi Ullah was a post-doctoral staff scientist at the Lawrence Livermore National Laboratory, CA, USA.
He has 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 radiation damage, non-adiabatic coupling of molecular vibrations with the substrate electrons (metal surfaces), defect dynamics, and plasmonics. He is also interested in studying matter under extreme (temperature and pressure) conditions using first-principles molecular dynamics and metadynamics. More recently he has been learning how to apply machine learning tools to material science problems.
He is also interested in the development and integration of numerical techniques into the pedagogical teaching of physics.
