Christopher Roland

Professor

Biography

Professor Roland received his PhD in Physics in 1989 from McGill University. He then spent a year as a postdoctoral fellow at the University of Toronto and at the AT&T Bell Laboratories Murray Hill facility. He joined NC State as an Assistant Professor in 1993, became an Associate Professor in 1998, and Professor in 2002. He is currently a member of the Center for High Performance Simulations (ChiPS).

Prof. Roland's research interests have been centered primarily in the area of theoretical Condensed Matter Physics. His initial work focused on understanding dynamics and growth phenomena in a variety of material systems, such as the kinetics of first order phase transitions, homoepitaxy of semiconductors, and the growth of carbon nanotubes.

More recently, research has focused on understanding quantum transport in molecular electronic systems for nanoscale applications and understanding select biomolecular systems. The work has a strong computational bend to it, employing a variety of numerical techniques aimed at understanding physical phenomena over different length and time scales.
