I’m an assistant professor at the University of Windsor focusing on theoretical condensed matter physics.

Most of my research falls under the broad heading of quantum magnetism, with some excursions into strongly correlated systems more generally. Recently I’ve been focusing on various realizations of frustrated magnets with strong anisotropy, such as found in rare-earth and heavy transition metal magnets. Some recent work is highlighted below. A full list of publications is available here.

Previously, I did post-doctoral research at the Max Planck Institute for the Physics of Complex Systems (2017-2019) and with Michel Gingras at the University of Waterloo (2014-2017). I received my Ph.D. from the University of Toronto (2008-2014) in the group of Hae-Young Kee, and my undergraduate degree from the University of Windsor (2005-2008).
