I am a Postdoc of CRC 326 - GAUS in the reserach group of Prof. Martin Möller.

I am interested in the complex algebraic and symplectic geometry of Higgs bundle moduli spaces and related topics. More recently, I am studying mirror symmetry questions about Higgs bundle moduli spaces and new approaches to compatified Jacobians and Prym varieties using logarithmic geometry. 

I did my PhD on the topic "Singular fibres of Hitchin systems" at Ruprecht-Karl Universität Heidelberg under supervision of Dr. Daniele Alessandrini and Prof. Dr. Anna Wienhard.

You can find more details in my curriculum vitae.

Workshop "Ramification in geometric Langlands and non-abelian Hodge theory"

September 9 - 13, 2024, University of Heidelberg, webpage.

This workshop is motivated by recent developments in geometric representation theory, related to wild ramification in the geometric Langlands program and non-abelian Hodge theory. The goal is to bring together researchers in these fields and researchers on irregular singularities (in particular Stokes phenomena), to stimulate future interactions.
