About Me
Steffen Löbrich
I am a postdoc at University of Amsterdam working with Miranda Cheng.
I recently completed my PhD in Mathematics at University of Cologne, supervised by Kathrin Bringmann.
My research interests lie in number theory, especially modular forms and harmonic Maass forms, and arithmetic geometry.
