Dr Steve Eichhorn

Steve Eichhorn graduated in Physics from the University of Leeds in 1993 and subsequently completed a Masters degree in Paper and Forestry Industries Technology at Bangor and UMIST in 1994/5. He then went on to do a PhD degree, graduating in 1999 on the subject of the "Deformation Micromechanics of Regenerated Cellulose Fibres". His academic appointments have been as a temporary Lecturer in the Department of Paper Science (then separate from the School of Materials) in 1997-8 and as a Visiting Research Scientist from 1998-1999. After this period he went to work under the supervision of Professor Bob Young as a postdoctoral research associate (1999-2002) and was appointed as a Lecturer in the Materials Science Centre in 2002. His research interests are at the interface between natural and biomaterials research with particular emphasis on cellulosic materials and composites. He has research projects that also investigate the structure property relationships of seashells and fingernails. In terms of techniques, Dr Eichhorn has particular expertise in the use of Raman spectroscopy, synchrotron x-ray diffraction and molecular dynamics/mechanics modelling of polymeric materials. He is a member of the ACS Cellulose and Renewable Materials division and the Institute of Physics.
