Hello, and welcome to my website! I am currently a postdoctoral fellow in the Department of Mathematics and Computer Science at Brandon University in Brandon, Manitoba, Canada working with Rory LucyshynWright. I obtained my PhD in mathematics at the University of Ottawa in October 2020 working with Pieter Hofstra and Philip Scott, and my MSc in Logic and Computation at Carnegie Mellon University in May 2015 working with Steve Awodey. My research interests lie primarily in category theory, topology, and logic.
