I am a postdoc at University of Duisburg-Essen in the working group of Prof. Dr. Vytautas Paškūnas.

Research interests

I am working on deformation theory of mod $p$ Galois representations of number fields with values in a reductive group $G$, as well as $G$-pseudocharacters and determinant laws for symplectic groups. Currently I am working on the trianguline variety for reductive groups and Zariski density of crystalline points in the generic fiber of deformation rings.

In preparation

The trianguline variety for reductive groups, with Andrea Conti and Mohamed Moakher.
Good moduli spaces for complex analytic stacks, with Ludvig Modin.
