I am on parental leave Fall 2025
I am an assistant professor at the University of Western Ontario in London Ontario, since 2022.
My research is in numerical algebraic geometry - I develop and use numerical algorithms for studying solutions to polynomial equations.
Current themes of my research include:
-Automation of algorithms for enumerative problems
-Analysis of randomized algorithms in numerical algebraic geometry
-Applications of probabilistic group theory to monodromy algorithms
-Low-memory methods for polynomial system solving
-Certification methods, verification methods, and heuristics in numerical algebraic geometry
