Hi! I am an assistant professor in the Department of Physics and Astronomy at BYU, where I have been since 2018. My research involves structural studies of interesting and useful materials using neutron, x-rays, and photons. I currently teach General Physics II (Physics 106) and Advanced Mechanics (Physics 321). Before beginning my current position, I was a postdoctoral researcher at UC Berkeley and Lawrence Berkeley National Laboratory, where I worked with Prof. Bob Birgeneau on neutron and x-ray scattering studies of iron-based superconductors. Prior to that, I performed my graduate studies at Columbia University in New York, where I was co-supervised by Profs. Tomo Uemura and Simon Billinge on muon spin spectroscopy and pair distribution function analysis of strongly correlated electron systems. And before that, I was right back here at BYU as an undergraduate, where I studied physics and German and did research with Prof. Branton Campbell on relaxor ferroelectric materials. I grew up in southern California and enjoy going back to visit whenever I can.

My wife and I have been married since 2011. She is a writer with an undergraduate degree in English from BYU and a master's degree in literature from the City University of New York. She is currently working on a masters of fine arts degree at BYU. We have three wonderful and vivacious children. Outside of work and family, my passions and hobbies include music (piano and cello), athletics (soccer and running), the outdoors (hiking, snowboarding), traveling, and working to make BYU a more inclusive and loving place.
