Current Projects

Thermal Physics Laboratory 
Professor D. G. Walker
The Thermal Physics Lab is dedicated to scientific discovery at the frontiers of heat transfer. Current research includes investigation of new transient thermometry using thermographic phosphors, modeling and simulation of noncontinuum energy transport in microelectronic devices, quantum energy conversion devices, radiation effects in nanostructures, and novel electronics cooling technologies. All efforts are grounded in fundamental thermo-physical processes but expand the boundaries of traditional heat transfer applications.
