Wyn Roberts, a student of the Amman Valley Grammar School, studied chemistry at University College Swansea where, after graduation, he pursued postgraduate studies investigating the role of sulphur as a catalyst in the formation of nickel carbonyl under the supervision of Keble Sykes. After being awarded his Ph.D he was first appointed to a United Kingdom Atomic Energy Research Fellowship at the Imperial College of Science and Technology, London, and then as a Senior Scientific Officer at the National Chemical Laboratory, Teddington. His first academic post was a lectureship at the Queen”s University, Belfast before in 1966 being appointed to the Foundation Chair of Physical Chemistry at the University of Bradford, where he also had periods as Head of Department and Dean of Physical Science. In 1979 he moved to University College, Cardiff where he was Head of Department (1987 to 1997), a Deputy Principal (1990-1992) and is currently a Research Professor. He was invited to be World Bank Visiting Professor in China in 1985, a Visiting Professor at Berkeley and is an Honorary Fellow of the University of Wales, Swansea. He was the first Chairman of the Surface Reactivity and Catalysis Group (SURCAT) of the RSC. Phil Davies, a student of Blythe Bridge High School, Stoke-on-Trent, studied chemistry and mathematics in Southampton University. An undergraduate project on modelling of adsorption at fractal surfaces led to an interest in surface phenomena and after graduating with double honours in 1986 he moved to Cardiff to study reactions at surfaces with surface sensitive spectroscopy. After being awarded his Ph D he was appointed to a lectureship in the department of chemistry at Cardiff. His main research interests are studying reaction mechanisms at surfaces primarily through the use of surface sensitive spectroscopy but he also spent a short period of time with Prof Rutger van Santen in Eindhoven studying adsorption and reaction using abinitio calculations on clusters. Since 1997 his interests have centred largely on the influence of local atomic structure on reaction mechanism studied with scanning probe microscopies. Between them Davies and Roberts have published over 400 scientific papers and a number of books.
