I am a theoretical physicist living in Oxford/UK.
I work as a postdoctoral research associate in the group of Erik Panzer at the Mathematical Institute, University of Oxford, and I am associate postdoc at Perimeter Institute for Theoretical Physics in Waterloo/Ontario.
My research interests include renormalization, non-perturbative effects, combinatorics and numerics. Details are explained under Research.
I studied physics in Jena, Lund and Berlin, and did my doctorate in physics under the supervision of Dirk Kreimer at Humboldt-Universität zu Berlin. Until 2024, I was postdoctoral fellow in the group of Karen Yeats, Department of Combinatorics&Optimization at the Faculty of Mathematics, University of Waterloo.
News
- Together with Stav Zalel, Alicia Castro, and Ian George, we are organizing a virtual workshop on combinatorics in fundamental physics, on November 26-29, 2024, hosted as part of the Youngst@rs programme at the MITP.
- Slides of my recent talk in Bonn about variations of Dyson-Schwinger equations.
- New preprint about a combinatorial proof of a Non-Renormalization Theorem similar to the Kontsevich formality theorem (joint with Davide Gaiotto)
- My doctoral thesis has appeared as Springer thesis. It is now also available as an ebook (and hence in many cases downloadable through libraries)
- New preprint about statistics of Feynman periods (joint with Kimia Shaban).
- I gave talks at the 2024 CAP Congress in London/ON and the Theory Canada 16 meeting in Waterloo/ON, at Amplitudes 2024 in Princeton/NJ and at the William Tutte Colloquium at Waterloo/ON . All slides are under Research.
