Dr Thomas Moller-Nielsen

College Lecturer in Philosophy
BSc, MSt, DPhil

Thomas Møller-Nielsen was an undergraduate at the University of Bristol and did his postgraduate work in philosophy at Balliol College, Oxford. He is currently a stipendiary lecturer in philosophy at Oriel.


In addition to the philosophy of physics, Tom's teaching interests include the philosophy of science, logic, metaphysics and epistemology, early modern philosophy, the philosophy of mind, and the philosophy of religion.

Research interests

Most of Tom's research is in the philosophy of physics and metaphysics, with a focus on broadly 'Leibnizian' themes as they arise in contemporary physics. He is particularly interested in the role played by symmetries and modern-day versions of the Principle of the Identity of Indiscernibles in the interpretation of physical theories; he also has research interests in the historical Leibniz and the metaphysical view, often ascribed to Leibniz, that the world is fundamentally purely qualitative in character ('generalism').
