I am interested in the theoretical foundations for persistence theory in topological data analysis and their applications to dynamical systems. For my research, I primarily exploit concepts from algebraic & combinatorial topology, (algebraic) combinatorics, metric geometry, commutative algebra, representation theory, and category theory, blending these with ideas of persistence in topological data analysis. I also often run into computational geometry & topology questions during my research.
