# About me

I am currently a temporary assistant professor at the University of Hawai‘i at Mānoa. Previously I was a postdoctoral scholar in mathematics at the University of California, San Diego, where I worked with Professor Kiran Kedlaya. I finished my PhD in 2015 at Indiana University under the supervision of Professor Matthias Strauch. I completed my BA at Swarthmore College.

# Research

My research belongs to the field of algebraic number theory. Specifically, I study (*φ*,*Γ*)-modules, a concept used to study *p*-adic Galois representations via Jean-Marc Fontaine’s equivalence between étale (φ,Γ)-modules and continuous **Z**_{p}-representations. Recently, I have been working with Kiran Kedlaya and Gergely Zábrádi to extend Fontaine’s equivalence to multivariate (φ,Γ)-modules, and to show that such modules are overconvergent. In my PhD thesis, I examined whether there exists a theory of (φ,Γ)-modules for the Lubin-Tate tower of deformation spaces of formal modules. This work drew on recent work of Anthony Scholl, which gives criteria under which such a theory of (φ,Γ)-modules exists.

For more details, see my research statement.
