I am an Assistant Professor in the Department of Physics and Astronomy at the University of Denver. I did my PhD research at the University of Colorado, a postdoc at NIST Boulder, and then came to DU in September 2010. I love teaching and thinking through challenging physics concepts, and I love doing research with lasers. Speciically, I use ultrafast pulsed lasers as "strobe lights" to observe energy transport in nanostructures, relevant to cooling of integrated circuits and solar energy harvesting.

My research interests lie in understanding transport of fundamental energy carriers in and near nanostructures. I use ultrafast lasers to make spectroscopic measurements of electron, hole, and phonon transport and interactions. I want to understand these processes in a variety of nanoscale systems, such as quantum-confined semiconductor systems and metal-on-insulator nanowires. These energy transfer processes are relevant to heat-sinking of nanocircuits and solar energy conversion.
