The next semester I will be visiting Andrés Sambarino at Jussieu as part of the Doc.Mobility Fellowship. Please get in touch if you will be in or around Paris and would like to talk!
Research interests
I am interested in differential geometry, Lie theory and Teichmüller theory. In particular, I like to think about discrete subgroups of Lie groups, for example of SL(n,ℝ).Preprints
- An incomplete real tree with complete segments [arXiv:2212.09640], joint with Raphael Appenzeller, Luca De Rosa, Victor Jaeck.
- Characterizing Hitchin representations over real closed fields [arXiv:2208.13611].
- Subrepresentations in the homology of finite covers of graphs [arXiv:2107.07428].
Editorial work
- Proceedings of the Young Researchers Workshop on Positivity in Lie Groups [arXiv:2212.04339], joint with Arnaud Maret.
