Researcher in Computational Mathematics and Statistics
Illinois Institute of Technology, Chicago
My name is Nathan Kirk, Senior Researcher at the Department of Applied Mathematics at the Illinois Institute of Technology, Chicago. Before that, I was a researcher in the Department of Statistics and Actuarial Sciences at University of Waterloo, Canada. I finished a PhD in Mathematics at Queen's University Belfast, Northern Ireland in 2023.
In January 2026, I will join the School of Mathematics and Statistics at the University of St Andrews as Associate Lecturer of Statistics.
My main research interest for the past number of years remains the optimization of sampling methodologies, particularly using ideas from state-of-the-art machine learning  algorithms. Specifically, I am primarily interested in optimized quasi-Monte Carlo sampling schemes which are, in some sense, representative of the underlying distribution. Additionally, I am increasingly involved with my collaborators on investigating what optimized sampling procedures can lend to problems from wider fields including algebraic statistics, and problems where uncertainty must be quantified, e.g., cardiology, nuclear fusion and finance.
