Duncan Shepherd is a Reader in Bio-medical Engineering.
Duncan has published over 70 peer-reviewed journal papers and book chapters in the field of Bio-medical Engineering, mainly on the design and testing of medical devices. He has received major grants from Arthritis Research (UK), Commission of the European Communities, Engineering and Physical Sciences Research Council and the medical device industry. He has been invited to give talks on his research in Canada, India, Malaysia and the UK.
His main areas of teaching are modules on mechanical engineering design and bio-medical engineering. He is the Director of Quality Assurance and Enhancement within the College of Engineering and Physical Sciences.
Duncan Shepherd gained a BEng in Mechanical Engineering from the University of Leeds in 1993. He went on to undertake research in Bio-engineering in the Research School of Medicine, University of Leeds. In 1997 was awarded a PhD for research on the mechanical properties of articular cartilage.
From 1997 until 2004 he worked in Department of Bio-Medical Physics & Bio-Engineering at the University of Aberdeen. He started work as a Research Fellow and in 2000 he was awarded a prestigious Leverhulme Trust Special Research Fellowship to undertake research on the design of a novel wrist implant. In 2002 he became a Lecturer in Bio-engineering.
Duncan moved to the University of Birmingham in 2004 as a Lecturer to help establish a new research area in Bio-medical Engineering, located within the School of Mechanical Engineering. He was promoted to Senior Lecturer in 2006 and Reader in 2011.
Bio-medical Engineering, Design and Testing of Medical Devices, Measurement of Mechanical Properties of natural tissues.
Spinal implant testing
With funding from the Engineering and Physical Sciences Research Council, Duncan has developed a spinal implant testing facility at the University of Birmingham. A spine simulator is being used to investigate:
Tribology of disc arthroplasty
Mechanical properties of elastomeric disc arthroplasty
Mechanical properties of nucleus replacement implants
Design of medical devices
Duncan has experience in designing a range of medical devices including small joint arthroplasty, sternal fixation devices and surgical instruments. He uses solid modelling and finite element analysis to optimise designs, and has experience of working within the regulatory framework for the design of medical devices. He also has a range of experience of using materials testing machines to test medical devices to International Standards.
Mechanical Properties of natural tissues
Duncan has experience of measuring a range of mechanical properties of natural tissues. This research has included measurements of the viscoelastic properties of articular cartilage and the intervertebral disc, using Dynamic Mechanical Analysis.
