Welcome!
Welcome to my webpage! I am a mathematician specialising in analysis, holding a professorship at the University of Konstanz (W1 to W3) since April 2021. Specifically, I am the successor of Prof. R. Racke (Chair of Analysis in Konstanz). A short CV is available here.
Broadly speaking, my research is centered around nonlinear PDEs and the Calculus of Variations. There are strong intersections with real analysis, function spaces and their interactions in applications. Here, a particular focus is on the borderline case of linear growth functionals, where things substantially differ from other frameworks - might it be because of compactness or failure of standard techniques from harmonic analysis.
Feel free to look around! For research papers, please look here, and for selected course material, please look here. Auxiliary material for students writing a thesis under my supervision can be found here.
NEWS & ACTIVITIES
Conference 'Calculus of Variations'
Cristiana De Filippis, Giuseppe Mingione, Simon Nowak and myself are organising the conference '(Ir)regularity at Parma' to take place in May 2026. More information will be made available soon.
Zeitschrift für Analysis und ihre Anwendungen
I recently joined the editorial board of ZAA (EMS press) - we are looking forward to receiving articles on new and thrilling developments. See here for more information.
Outreach talks: Prof@School
I am part of the prof@school program. If interested, I am happy to deliver a talk at your school - topics can be found at the official university site here.
DMV-Conference 2026
I am one of the main organisers of the Main Conference of the German Mathematical Association in 2026. For more information (and the submission of proposals for, e.g., minisymposia), have a look here.
Theses, Winter Term 2025/26
In Winter 2025/26, I have reached my maximum capacity for supervising students - see here for the current team. In order to provide all of my students with a reasonable supervision, I have thus decided to not accept quests for new theses.
If you aim to write a graduation thesis (BSc or MSc) in Winter 2025/26, please contact my colleagues, e.g.
Prof. Robert Denk or Prof. Markus Kunze.
Conference 'Calculus of Variations'
In February (Feb 17-21, 2025), Cristiana De Filippis (Parma), Filip Rindler (Warwick) and I organised a conference on the Calculus of Variations, celebrating Jan Kristensen's 60th birthday. See here for more information.
Mini-course 'Korn inequalities: Old & new'
In May 2024, I give a mini-course on Korn inequa-lities at TU Darmstadt. The course aims to give an accessible survey of both classical material and re-cent developments.
Conference on Partial Differential Equations
For March 2025, Matthias Hieber, Markus Kunze, Reinhard Racke and I are organising a workshop on the occasion of Robert Denk's 60th birthday. More information will be available soon.
Cabin Seminar 'Fourier Analysis'
In winter term 2024/25, I offer a cabin seminar in Pfitztal (Austria) on the broad theme of Fourier analysis. All free slots are booked. For further information, please contact my assistants Lukas Fußangel and Paul Stephan.
