Zack Cramer

PhD, Pure Mathematics


Welcome! My name is Zack (he/him/his), and I'm a Lecturer in the Mathematics Undergraduate Group at the University of Waterloo.

I completed my MMath (2015) and PhD (2020) in Pure Mathematics at the University of Waterloo under the supervision of Laurent Marcoux.
