Tom McLeish FRS
Professor of Natural Philosophy



Tom McLeish, FRS, is a physicist, academic interdisciplinary leader, and writer. He is inaugural Professor of Natural Philosophy in the School of Physics, Engineering and Technology at the University of York, England, and is also affiliated to the University’s Centre for Medieval Studies and Humanities Research Centre.

His scientific research in ‘soft matter and biological physics,’ has inspired collaborations with chemists, engineers, and biologists to study relationships between molecular structure and emergent material properties, recognized by major awards in the USA and Europe. He has conceived, won funding for, and directed several large interdisciplinary collaborations and currently leads the UK ‘Physics of Life’ network. He holds a 5-year ESPRC personal research fellowship focusing on the physics of protein signalling and the self-assembly of silk fibres.

His interdisciplinary academic interests include the framing of science, theology, society and history, and the theory of creativity in art and science, leading to the recent books Faith and Wisdom in Science (OUP 2014) and The Poetry and Music of Science (OUP 2019). He co-leads the Ordered Universe project, a large interdisciplinary re-examination of 13th century science. He has also contributed to the philosophy of emergence, and to research in cross-curricular education for post-16 pupils.

From 2008 to 2014 he served as Pro-Vice-Chancellor for Research at Durham University and was from 2012-2015 Vice President for Science at the UK Institute of Physics, and from 2015-2020 Chair of the Royal Society’s Education Committee. He is currently a Council Member of the Royal Society, a trustee of the John Templeton Foundation, and chair of Harvard University’s Knox postgraduate awards.

He gives frequent public lectures in literature and science festivals, and in schools, on topics across the sciences and humanities, and regularly appears on local and national radio.

My research maintains a core of soft-matter and biological physics, especially concerning the role of random processes in protein dynamics, self-assembly of bio-molecular fibres and in evolution itself. I also retain an interest in molecular rheology – the physics of complex fluids such as polymer melts and their flow-properties. Currently these two fields are combining in the flow and self-assembly of silk.

I also have broad interdisciplinary research interests concerning science within wider historical and cultural contexts. These include collaborative work on medieval science (especially through the international interdisciplinary Ordered Universe project on the scientific works of Robert Grosseteste), the philosophy of strong emergence (including a contribution to the Routledge Encyclopaedia of Emergence), the entanglement of science with literature (for example, the book Poetry and Music of Science – OUP 2019), and the theology of science (currently through the major project with St. John’s College Durham Equipping Christian Leadership in an Age of Science and the book Faith and Wisdom in Science – OUP 2014)
