### Research Interests

My research interests are in number theory, representation theory, and algebraic geometry:

- Galois representations and pseudorepresentations, families and deformations
- P-adic Hodge theory: integral theory, families and deformations
- Eigenvarieties

### Papers and Preprints

Thesis: Moduli of Galois Representations. Version 1.1. [pdf]
