## Welcome!

I am currently an assistant in the Computational Arithmetic Geometry Group at the University of Heidelberg.

Before that I worked as a postdoctoral fellow at the Max Planck Institute for Mathematics and in

the Arithmetic Algebraic Geometry group of the University of Bonn.

In 2014, I completed my Ph.D. at Imperial College London under the supervision of Prof. Kevin Buzzard .

I am interested in the Langlands programme via arithmetic geometry.

In particular, I am interested in the

In particular, I am interested in the

*p*-adic and mod*p*aspects of Langlands functoriality. I like to study*p*-adic functoriality using non-archimedean geometry, e.g. via eigenvarieties and using the theory of rigid analytic spaces or through towers of (local) Shimura varieties using the theory of perfectoid spaces.## Preprints
