I am on parental leave Fall 2025
I received my PhD in mathematics from 'Texas A&M University' under the guidance of Frank Sottile. Afterwards (2020), I traveled to the 'Max Planck Institute for Mathematics in the Sciences' in Leipzig, Germany to join Michael Joswig's software group. In 2021 I came back to the US to work with Jonathan Hauenstein at the 'University of Notre Dame' as a postdoc. Since 2022, I have been an assistant professor at the University of Western Ontario in London Ontario.
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
