Dr Gwen Reilly BSc DPhil


Lecturer in Tissue Engineering

Tel: +44 (0)114 222 5986

Dr Gwendolen Reilly was appointed as Lecturer in Tissue Engineering in 2004. Previously she was a Research Assistant Professor in Bioengineering at the University of Illinois, Chicago. She has undertaken post-doctoral research at the University of Pennsylvania, Pennsylvania State College of Medicine and the Swiss Federal Institute of Technology. Gwen received her DPhil in Biology at the University of York, specializing in bone biomechanics.

Gwen combines her previous experience of cell biomechanics, biomaterials and cell differentiation to examine the effects of mechanical stimulation in the tissue engineering of bone and cartilage. She is interested in how skeletal cells respond to a mechanical stimulus by organizing the proteins and mineral they secrete in a way which enhances the strength of the matrix. The results of this research will have applications in orthopaedic and dental medicine, where clinicians are looking for improved methods to repair bone and cartilage.

Dr Russell Goodall


Senior Lecturer in Metallurgy

Tel: +44 (0) 114 222 5977

Dr Goodall's research is centred around metal foams.  These are metals containing large amounts of distributed, interlinked porosity, which gives them many interesting and unusual properties.  Among these is the fact that metal foams can have a very large surface area to volume ratio, and treatments affecting this large specific surface area can have a significant impact on foam properties.
Within the Leonardo Centre, work is looking at how surface treatments and coatings may be applied to different types of metallic foams, and the affect these have on properties.  In the case of Plasma Electrolytic Oxidation for example, it has already been shown that significant improvements in the strength to density ratio can be achieved.

Dr Adam Beagles


EU FP7 SustRail project looking at sustainability of rail freight transport


He's been modelling the effect if rail-wheel contact loading in track component life, and how this could be improved through better management of the contact (e.g. lubrication and friction management at the rail-wheel intereface). He's also looking at aerodynamic performance of rail freight vehicles.
