Assistant Professor of Physics, University of Oregon

Welcome to my site!

I am an assistant professor at the University of Oregon in the Department of Physics and a member of the Institute for Fundamental Science. My research is in particle physics phenomenology and I am interested in understanding the nature of dark matter. Dark matter comprises nearly 85% of the known matter content of the Universe, but its identity remains a mystery. Specifically, I focus on methods and techniques of detecting various candidates of dark matter. I am a co-founder of the SENSEI experiment, which uses silicon CCDs to look for dark matter candidates that are less massive than a proton. In addition, I investigate the potential of astrophysical and cosmological probes to detect models of ultralight dark matter. You can find a list of my publications at INSPIRE-HEP

Since arriving at UO, I created -- in collaboration with Prof. Kate Kelp-Stebbins and the UO Comics Studies program -- the UO Science and Comics Initiative. You can read more about the initiative here!
