My research interests are in geometry, topology, and their applications. In particular, I am focused on inverse problems for topological and geometric invariants, topological optimization and approximation, learning with topological invariants, and the connections between them. I have also been working in the area of data fusion, using techniques from geometry and topology to analyze and synthesize time series data.

From Geometry to Topology: Inverse Theorems for Distributed Persistence (with Alex Wagner and Paul Bendich) [arXiv]
We propose a distributed persistence invariant which provably interpolates between geometry and topology.

A Fast and Robust Method for Global Topological Functional Optimization (with Alex Wagner and Paul Bendich) [arXiv]
We propose a new framework for optimizing topological functionals on simplicial complexes that is faster, and produces more robust optima, than prior methods.

Geometric Fusion via Joint Delay Embeddings (with Paul Bendich) [Fusion2020]
We use geometric and topological methods to fuse time series.
