Alex is Clinical Senior Lecturer in Orthopaedic Surgery at the MSK Lab, based at the Sir Michael Uren Hub on the White City Campus, and Consultant Orthopaedic Surgeon at St Mary's and Charing Cross Hospitals. His principal research interest is in the improvement of joint replacement surgery through the use of big data and new technologies. In particular, he is interested in technological approaches to the prevention and management of infection following joint replacement, and in the improvement of outcomes of partial knee replacement.

After studying medicine as an undergraduate at Imperial, Alex completed his basic and core surgical training in West London before joining the North West Thames Orthopaedic Higher Training Programme in 2010. Between 2011 and 2014 he undertook a DPhil (PhD) at the Univeristy of Oxford as an Arthritis Research UK / Royal College of Surgeons research fellow, under the supervision of Prof. David Murray, Prof. Hemant Pandit, Prof. Andy Judge and Prof. Richie Gill. His thesis, entitled "Failure of Unicompartmental Knee Replacement" was published in 2015 and resulted in a number of influential publications on the use of partial knee replacement.

Following his DPhil, Alex was appointed NIHR Clinical Lecturer at University College London, based at the Institute of Orthopaedics and Musculoskeletal Sciences at the Royal National Orthopaedic Hospital. Here he set up a study using advanced imaging technology better to understand the formation of biofilms on infected hip and knee replacements, in collaboration with Prof. Dave Spratt at the Eastman Dental Institute and funded by grants from Orthopaedic Research UK and the Royal College of Surgeons of England. Alongside this, in collboration with Mike Whitehouse at the University of Bristol, he conducted a study into the effect of implant materials on the rate of infection following knee replacement, using data from the National Joint Registry for England and Wales.
