John Finney is Emeritus Professor of Physics at University College. His Ph.D. on liquid structure was supervised by J.D. Bernal in the Crystallography Department at Birkbeck College London, where he was subsequently awarded a personal chair in Crystallography. His research has focussed on liquids and disordered solids, with particular reference to water and aqueous solutions, and the role of water in chemical and biological functionality. In 1988 he was appointed Head of Neutron Science, and subsequently Chief Scientist, at the ISIS Pulsed Neutron Facility, moving to the Quain Chair of Physics at UCL in 1993 to found the Condensed Matter and Materials Physics group. He is a Fellow of both the Institute of Physics and the Royal Society of Chemistry and past Vice President of the British Crystallographic Association. A founder-member and past Vice President of Euroscience, he was Founder Editor of Euroscience News.
In addition to some 300 scientific research papers, he is the author of Water: A Very Short Introduction, published by Oxford University Press. The book provides an introduction to the science of water, ice, snow, and steam, and how the structure of water molecules gives rise to its physical and chemical properties.
