Christoph Stephan

Christoph Stephan is a scientific researcher at the Institute of Mathematics, University of Potsdam, where he has held a permanent position since 2022, following prior service from 2006 to 2017. He bridges mathematics and theoretical physics, focusing on noncommutative geometry and its applications to fundamental physics. His work integrates advanced geometric frameworks with particle physics, particularly the Standard Model and its extensions.

Christoph Stephan's research centers on noncommutative geometry, where he explores how geometric frameworks can unify general relativity and the Standard Model. His interests include Dirac operators, torsion in gravity, finite spectral triples, and Krajewski diagrams for classifying particle models. He has developed extensions of the Standard Model that incorporate new scalar fields, dark matter candidates, and neutrino mass mechanisms such as the inverse seesaw. His work often investigates the spectral action principle and its implications for coupling constants and Higgs mass predictions.

The 15 most recent publications reflect a consistent focus on mathematical structures in particle physics. They span topics from the geometric unification of forces to torsion gravity and Beyond Standard Model phenomenology. A recurring theme is the use of noncommutative geometry to derive or constrain physical models, often with testable predictions. The publications reveal strong collaboration with experts like Frank Pfäffle and Thomas Schucker, and a deep engagement with both theoretical formalism and phenomenological implications.

While no explicit scientific awards are mentioned in the provided text, his extensive publication record in top journals such as Communications in Mathematical Physics, Physical Review D, and Journal of Mathematical Physics attests to significant scholarly recognition.

Christoph Stephan has advised or collaborated with several researchers in his field, though formal student advisees are not listed. His work has been supported through academic positions and research time, particularly at the University of Potsdam and during his postdoctoral phase in Marseille. He has also worked in industry as a consultant at d-fine, applying analytical skills to capital markets and regulatory projects.

He is associated with a KI-Labor (AI Lab) at the University of Potsdam, indicating an interest in applying artificial intelligence and proof assistants to mathematical research. This lab likely serves as a hub for interdisciplinary work combining formal methods, logic, and geometry. His research group or collaborations involve physicists and mathematicians working on spectral triples and model building beyond the Standard Model.
