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.
