Mathematics in Physics and Philosophy Group

Dr. Siddhant Das studied electronics and communications engineering and pursued his graduate training at LMU Munich, where he has been affiliated with the Arnold-Sommerfeld Center for Theoretical Physics. He completed the elite graduate course in theoretical and mathematical physics jointly organized by LMU Munich and the Technical University of Munich (TUM), earning an MSc degree. His master’s thesis, supervised by Prof. Dr. Detlef Dürr, was devoted to the study of arrival-time distributions of spin-1/2 particles. Since 2010, he has been a doctoral student in the Workgroup Mathematical Foundations of Physics at the Mathematisches Institut at LMU Munich under the supervision of Prof. Dr. Detlef Dürr, where his doctoral research focuses on quantum arrival times and time-of-flight measurements within rigorous frameworks of mathematical physics. His research interests lie in the mathematical and conceptual foundations of quantum mechanics, with particular emphasis on temporal observables, relativistic quantum mechanics, and analytically controlled models of quantum measurement.

PD Dr. Dirk-André Deckert studied Physics at the LMU Munich and, as a DAAD fellow, at the University of Queensland in Brisbane, Australia. After his doctoral studies, funded by the BayEFG initiative, now the Elite Network of Bavaria, he received his doctorate in Mathematics at the LMU Munich in 2010. His doctoral thesis "Electrodynamic Absorber Theory" comprises a mathematical and physical investigation of radiation reaction and electron-positron pair creation. His main research and teaching activities lie within Mathematical Physics and Applied Mathematics and focus, especially on Mathematical Quantum Field Theory and Mathematical Learning Theory. For one year, he conducted research as a post-doc fellow of the DAAD at the University of California Davis, where he was later appointed as Arthur J. Krener Assistant Professor for three years before commencing his work in the Elite Network of Bavaria in Munich. At the Department of Mathematics at LMU Munich he is part of the Stochastics Research Group where he wrote his habilitation "On three known deficiencies of Mathematical Quantum Field Theory".

Fabian Nolte, MSc is a doctoral student working on regularization and dressing techniques in mathematical (quantum) field theory, with a particular focus on a time-dependent version of the Van Hove–Miyatake model. In addition, he is broadly interested in the foundations of quantum theory.

Dr. Paula Reichert studied physics, mathematics, and philosophy at the University of Munich (LMU) where she also received her doctoral degree (in mathematical physics) in 2018. Her dissertation was dedicated to the statistical analysis of gravitating systems and relationalist theories of gravity (shape dynamics). It was supervised by Prof. Dr. Detlef Dürr. After her doctoral studies, she had several scholarships and held different postdoctoral positions in both mathematics and philosophy, before she became a full lecturer in mathematics at the LMU in 2023. Since 2025 she is also a member of the metaphysics chair in philosophy. Her research is focused on the mathematical and conceptual foundations of physics and metaphysics.

Jago Silberbauer, MSc focuses his research on mathematical foundations for machine learning. More specifically, he works on higher-order Markov chains, Markov decision processes, and stochastic approximation, with a particular interest in probabilistic structures in discrete systems, state-space reductions, and the infinite-layer limits of neural networks. Beyond his academic work, he is an avid science fiction enthusiast and board game buff who enjoys exploring imaginative worlds both in theory and at the gaming table.
