I am currently an assistant professor in the Department of Mathematics and Statistics at St. Francis Xavier University. In addition, I am currently a research scientist in the SHEA (Substance Use and Health in Emerging Adults) Lab in the Department of Psychology at St. Francis Xavier University.
My current research areas include inverse semigroups, category theory, groupoids, restriction categories, spatial statistics, and policy research surrounding cannabis and alcohol use.
