Scott has over 15 years’ experience in musculoskeletal research and is an internationally recognised member of the research field. He conducted seminal work characterising the biochemical events surrounding bone formation and in particular investigating the role of a novel enzyme, PHOSPHO1, in the mineralisation process. Scott discovered substrates for this enzyme and proposed its role in matrix vesicle-mediated bone mineralisation. This concept has now been tested and replicated in multiple labs across the globe. Scott also has a wealth of experience in skeletal stem cell signalling and the effect of signal modulation on bone tissue formation. This work was initiated at the KU Leuven (Belgium), where he used transcriptomic analysis of in vivo events to define regulators of tissue formation that could be used to prime stem cells for repair and regeneration. During his time in Belgium, Scott was awarded a fellowship from the Scientific Research Council of Flanders (Fonds Wetenschappelijk Onderzoek – Vlaanderen). In September 2013, Scott was recruited to form a research group at the UCL Institute of Orthopaedics and Musculoskeletal Science, University College London (UCL). In January 2016 Scott moved to UCB Pharma as a Senior Principal Scientist. During his time at UCB Scott identified musculoskeletal drug targets and led subsequent drug discovery efforts. Furthermore, he supported the development of Bimekizumab and Romosozumab clinical programs through the contribution of insight/data on skeletal biology/disease. In August 2019 Scott was appointed Senior Lecturer in Translational Musculoskeletal Research at the Royal Veterinary College, University of London.

Scott's research group aims to define the mechanisms of musculoskeletal development, disease and repair. The overall goal of his research is to identify and target cells and pathways to control bone and cartilage regeneration. Scott also has a long-standing interest in creating laboratory-grown models of skeletal tissues for the testing of biopharmaceuticals and compounds that may have applications to skeletal disease.
