Roger helps run the Tendon Biology Group at the Hawkshead campus with Dr. Jay Dudhia and which has received more than £5 million in research funding.  His main research interests are understanding the pathogenesis of tendon disease, diagnostics for musculoskeletal disease, and stem cell therapy for tendons in both horses and humans.

Roger is involved in both undergraduate (BVetMed) and postgraduate teaching.  For undergrduate teaching he teaches on the locomotor module and during clinic rotations in equine surgery.  At a postgraduate level he is involved in Resident (Senior Clinical Training Scholar) training where he has supervised or helped train 15 residents in equine surgery (with 2 more currently in post) with 100% pass record with the ECVS, 2 in Equine Practice and Orthopaedics, and 2 in Diagnostic Imaging.  In research, he has successfully supervised 6 PhD students (with two currently in post).  he is also heavily involved in delivering CPD to veterinary practitioners both nationally and internationally.

In addition to running a research group investigating tendon disease in horses and humans, Roger provides specialist orthopaedic referral services at the Royal Veterinary College's Equine Referral Hospital, where he is involved in lameness diagnosis, imaging and orthopaedic surgery.

Roger acts as Resident Ombudsman for the European College of Veterinary Surgeons.
