The Radiative Energy Transfer Lab (RETL) is part of the Department of Mechanical Engineering at the University of Utah. The missions of the RETL are: (1) to provide to the scientific community a fundamental understanding of radiative transfer at nanoscale, (2) to bridge the fundamental physical concepts and the engineering applications by developing cutting-edge radiation-based devices in diverse areas such as energy conversion, and (3) to educate highly qualified personnel.

Research at the RETL is multidisciplinary at the interface of mechanical engineering, applied physics, electrical engineering, materials science and mathematics. Current applications of interests include thermophotovoltaic power generation, near-field radiative heat transfer modeling in 3D complex geometries, design of materials with unique radiative properties, optical characterization of nanostructures, near-field thermal spectroscopy and radiation-conduction transition.

If you have any questions or if you are interested in joining the RETL, please feel free to contact Prof. Francoeur via e-mail (
