I am a PhD student at the Max Planck Institute for Mathematicsin Bonn since early 2020. My supervisor is Don Zagier. I did my MSc at the Technical University of Darmstadt under the supervision of Nils Scheithauer.

I am mainly interested in number theory, modular forms and their applications.

In particular, I am fascinated by different types of modularity, like mock- or quantum-modularity, and their appearance in different contexts.

In my PhD project, I intend to study so-called Nahm Sums (cf. §II.3), hypergeometric sums, which occur for example as characters of conformal field theories.
In some cases, Nahm Sums are known to be modular functions, but a precise characterization of modularity is quite not known.

In my PhD project, I aim to understand the modularity properties of those and similar sums.

My master thesis deals with symmetric modular forms for the Weil Representation and was supervised by Nils Scheithauer. Therein, we found a dimension formula for the vector space of symmetric modular forms if the underlying discriminant form is of a certain type.
