My research is in computational topology and topological data analysis, with a focus on algorithms for persistent homology. I am particularly interested in combinatorial reductions of simplicial complexes and filtrations, such as strong collapses and edge collapses, that preserve relevant topological and persistence information.
More broadly, I work on problems at the interface of algebraic topology, computational geometry, and algorithms.
Current directions include filtered and directed complexes, multiparameter persistence, and topological methods for studying temporal dynamics, neural activity, and collective choice. This work is supported in part by an ANRF ARG Matrix Grant, 2026–2031.
