Michael W. Finnis is a British materials scientist who is Professor of Theory and Simulation of Materials at Imperial College London. He uses atomic-scale computation to understand atomic interactions, grain boundary embrittlement and open system thermodynamics. He was elected Fellow of the Royal Society in 2021, and awarded the Institute of Physics Dirac Medal in 2022.
Finnis was born in Margate. He studied natural sciences at the University of Cambridge, where he specialised in theoretical physics. He remained in Cambridge for his doctoral research, working with Volker Heine on condensed matter physics.[1] His PhD investigated interatomic forces in simple metals.[2] He started working on tight-binding models, and that the total bonding energy of transition metals scaled with the square root of the coordination number (z).
Finnis spent fourteen years in the Atomic Energy Research Establishment. He developed theoretical and computational approaches to support the nuclear power industry. When he started working at the AERE, he used an IBM System/360, and eventually a Cray-1. Finnis developed Finnis–Sinclair potentials, which transformed simulations of metals. Finnis–Sinclair potentials took into account the local density dependence of atomic interactions through two terms: the first a short-range repulsive interaction, the second an attractive force described by the square root of a sum of pair of interactions between neighbours. In 1988 he was appointed an Alexander von Humboldt Fellow at the Fritz-Haber-Institut.[3] Finnis eventually moved to the Max-Planck-Institut für Metallforschung, where he started working on the science of interfaces. In 1995 Finnis and Ruth Lynden-Bell
In 2006, Finnis joined Imperial College London, where he co-founded the Thomas Young Centre for the Theory and Simulation of Materials. His research involves atom-scale computational models to understand the electronic and optical properties of materials.[5] c
