Steve Matcher joined the department as lecturer in biomedical engineering in October 2006. Previously he was with the biomedical physics group at the University of Exeter and before that he worked as a research fellow at the Department of Medical Physics and Bioengineering, University College London.
Steve Matcher's main interest is in the development and application of novel biophotonic tools to aid the characterisation of biological tissues. Photonics offers many unique advantages over other imaging techniques for studying biological systems, including structural and functional contrast, cellular level resolution, speed, non-destructiveness and cost. The group´s work focuses on techniques offering high resolution such as optical coherence tomography (OCT) and non-linear laser scanning microscopy. Facilities include Doppler and polarisation OCT systems plus supercontinuum and titanium-sapphire light sources to allow cellular resolution OCT imaging. The group works closely with the Tissue Engineering group within the Kroto Institute (Prof S MacNeil) and with the III-V device fabrication group within Dept of Electrical and Electronic Engineering (Prof R Hogg). Ongoing collaborative links also exist with the Dental School (Dr A Crawford, Dr K Hunter) and with the Dept of Mechanical Engineering (Prof Roger Lewis and Dr Matt Carré). He has provided consultancy services to GlaxoSmithKline and is presently working with Kirkstall Ltd (a bioreactor developer). In 2011 he undertook a Royal Academy of Engineering industrial secondment with Michelson Diagnostics Ltd, a leading developer of clinical OCT imaging equipment.
