Research
I am interested in geometry and topology in low-dimensions, with a special focus on understanding their mutual interactions using analytic tools. My work is partially supported by NSF grant DMS-2203498.

- Divergence-free framings of three-manifolds via eigenspinors.
- Topology of the Dirac equation on spectrally large three-manifolds.
- Homology cobordism and the geometry of hyperbolic three-manifolds.
