Dennis Lehmkuhl

Research Assistant Professor of History and Philosophy of Science
MSc., Imperial College London, 2003; M.A., Hamburg University, 2006; DPhil., Oxford University (Oriel College), 2009. Visiting Associate, Caltech, 2010, 2012, 2015. Caltech, 2015-18.

Dennis Lehmkuhl's work focuses on the history and philosophy of physics, specifically of spacetime theories. He has worked on Einstein's interpretation of general relativity and other spacetime theories, and on the question of how his positions square with the modern debates in the foundations of spacetime theories. He is particularly interested in questions like the status of the equivalence principle, the geodesic theorem, and how general relativity shold be interpreted as compared to alternative spacetime theories like scalar-tensor theories, the relativistic extensions of Modified Newtonian Mechanics (MOND), or classical unified field theories based on geometric generalisations of pseudo-Riemannian geometry.

As of 2015, Lehmkuhl is Scientific Editor at the Einstein Papers Project, which annotates and publishes the Collected Papers of Albert Einstein with Princeton University Press. He is currently working on Volume 15, which spans the years 1925-1927. He believes that this will be a particularly interesting volume: among other things it covers the birth years of modern quantum mechanics and Einstein's correspondence on this with Heisenberg, Schroedinger, Born and Jordan, Einstein's first paper (co-written with Jakob Grommer) on the problem of motion in GR, and so far virtually unknown correspondence between Einstein and Hans Reichenbach and Yuri George Rainich on the interpretation of spacetime theories.

Lehmkuhl graduated with a DPhil from the University of Oxford in 2009, after graduate studies at Imperial College London, the London School of Economics and the University of Hamburg. Before joining Caltech, Lehmkuhl had been a Departmental Lecturer at the University of Oxford, a Junior Professor at the University of Wuppertal in Germany, and a visiting fellow at the Center of Philosophy of Science at the University of Pittsburgh.
