I graduated from University College of North Wales and then carried out a PhD at Leeds University before moving to UCL where I spent over 25 years as a Biomedical Engineer. During my time at UCL I worked at the Royal National Orthopaedic Hospital where I developed and translated a number of orthopaedic implants into clinical practice. I am a past President of the British Orthopaedic Research Society. I have been awarded the UCL prize for enterprise and innovation, an NHS innovation award and the UCL consultants award. I sit on a number of scientific advisory boards and have been involved in the generation of three spin out companies. I hold several patents. I have published over 200 peer reviewed scientific papers and a number of book chapters. I have successfully supervised over 30 PhD and MD students.

My current research investigates the reattachment of tendons to bone and to implant surfaces, the integration of implants with the skeleton, the wear of implant bearing materials and the use of bone graft substitute materials.  Recent research has focused on the design and development of transcutaneous implants, which have transformed the lives of amputees.
