Research Keywords
Molecular dynamics simulations, Radiation damage, liquids, glasses, disordered materials
Research Interests
I am particularly interested in the physics of liquids, amorphous solids, disordered magnetic systems, liquid-glass transition, as well as effects of radiation damage in materials and its effect on materials use in nuclear and fusion applications. This is discussed on my personal website in more detail.
