I am a Ph.D. student at Heidelberg University and a member of the research group “Physical Mathematics” of Prof. Dr. Johannes Walcher.

I’m interested in dualities and mathematical structures that naturally arise in quantum field theories and string theory. During my Ph.D. project I particularly concentrate on the emergence of knot homologies in topologically twisted quantum field theories and investigate their holographic duals. Related fields of interest include topological quantum field theory, string dualities, mirror symmetry and physical interpretations of the Geometric Langlands correspondence.

The schedule for our semi-regular group meeting is here.

As a member of the STRUCTURES cluster of excellence, I help maintain a wiki on topological data analysis for the exploratory project EP Data and Mathematics. The goal of this EP is to bridge the gap between mathematicians, who are fluent in algebraic topology but usually lack real-world data, and scientists who have real-life data but may be put off by a perceived high initial expenditure when entering the field of topology. If you are interested in this story, feel free to get in touch and make sure to have a look at our Journal Club.

Together with Daniel Spitz and Maximilian Schmahl I am currently organizing the 2nd Workshop on Topological Methods in Data Analysis. This year we will offer an in-depth course on the gudhi library as well as three invited lectures by experts in the field.
