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

My interests lie in complex and differential geometry. More precisely, I am interested in Higgs Bundles, Hitchin Systems, Harmonic Maps and Representations of Surface Groups.

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

You can find more details in my curriculum vitae.

Workshop series "The geometry of sheaves: From derived categories to Higgs bundles"

We are organizing a series of one-day workshops at Frankfurt university in summer term 2022 covering topics in the realm of moduli spaces of vector- and Higgs bundles, representation varieties and non-abelian Hodge theory. You can find more information here .
