Malcolm is a National Institute for Health Research (NIHR) funded clinical lecture in surgery and a senior colorectal surgical specialist registrar at the University of Southampton, United Kingdom. He has completed a PhD in exercise physiology, perioperative surgical risk stratification and mitochondrial energetics. During his PhD Malcolm was the Clinical Lead for the Perioperative CardioPulmonary Exercise Testing service at University Hospitals Aintree, Liverpool, UK. His main aim is to improve post-operative outcomes in patients undergoing major surgery. He is achieving that by reducing the variability around perioperative risk stratification and by utilising tailored multimodal prehabilitation interventions. His research interests include interrogating the pathophysiological mechanisms of changing fitness and mitochondrial function with cancer therapies and the implementation of prehabilitation interventions to rescue and improve metabolic health, physiology, morbidity and cancer outcomes. Malcolm has published extensively in the perioperative medicine and surgical risk arena with significant high impact papers published in the past few years. Malcolm was awarded the British Journal of Surgery, John Farndon Prize in 2015 and again in 2017 for his research in predicting surgical outcomes using CardioPulmonary Exercise Testing. Malcolm is a senior co-investigator for WesFit – The Wessex Fit-4-Cancer Surgery Trial and is chief investigator for the FrOGS study (Frailty and Sarcopenia Outcomes in Emergency General Surgery), the first trainee led and delivery study in Wessex.
