Prof. Dr. Dennis Lehmkuhl

Dennis Lehmkuhl is Lichtenberg Professor of History and Philosophy of Physics at the University of Bonn. His work focuses on theories of gravity, spacetime structure, and how they interact with matter. He is a passionate proponent of integrated history and philosophy of physics; he has worked on Einstein's interpretation of general relativity and of other spacetime theories, and on the question of how Einstein's positions square with the modern debates in the foundations of spacetime theories. He is particularly interested in the analysis and interpretation of black hole physics and gravitational wave physics.
Prof. Lehmkuhl has been an Editor of Albert Einstein's Collected Papers since 2010, and spent 2015 to 2018 as the only full time Scientific Editor at the Einstein Papers Project. Before that, he was a Departmental Lecturer at the University of Oxford, a Junior Professor at the University of Wuppertal, and a visiting fellow at the Center of Philosophy of Science at the University of Pittsburgh. He graduated with a DPhil from the University of Oxford in 2010, after graduate studies at Imperial College London, the London School of Economics and the University of Hamburg. Here is a complete CV.
