Background

Biography

Matt is an Associate Professor of Physics at Oregon State University. His undergraduate degree is from the University of Toronto, and his PhD from the University of California, Berkeley. Matt was a Kavli Postdoctoral Fellow at Cornell University, and he started the Micro-Femto Energetics Laboratory at Oregon State University in 2014. His lab studies transport and spectroscopy in condensed phase materials and devices. His Micro-Femto Energetics Lab can resolve electronic relaxation, transport, and energy transfer occurring on femtosecond (10-15 s) timescale with sub-micron (<10-6 m) spatial resolution. Unconventional ultrafast microscopy approaches such as ultrafast-resolved photocurrents serve to optimize energy efficiency in emerging solar materials and better harness the potential of new quantum materials.
