I am Professor of Physics and Pro-Vice-Chancellor for Research and Innovation at the University of Sheffield. My first degree and PhD in Physics both come from Cambridge University, and following postdoctoral work at Cornell University, U.S.A., I was a lecturer at the University of Cambridge’s Cavendish Laboratory. In 1998 I moved to the University of Sheffield. I am an experimental polymer physicist who specialises in elucidating the nanoscale structure and properties of polymers and biological macromolecules at interfaces. I also have an interest in public engagement with science and in the wider issues surrounding the relationships between science, innovation and society, especially in connection with nanotechnology. I am currently a member of EPSRC Council, I was elected a Fellow of the Royal Society in 2006, and in 2009 I was awarded the Tabor Medal of the Institute of Physics for contributions to nanoscience.
