Malcolm is an academic surgeon specialising in complex cancers. He completed a NIHR funded PhD in exercise physiology, perioperative risk stratification, prehabilitation and mitochondrial energetics.

He aims to improve outcomes in patients undergoing major cancer surgery utilising personalised risk stratification and tailored multimodal prehabilitation interventions. His research interests include interrogating the pathophysiological mechanisms of changing fitness, nutrition, and body composition with cancer therapies, whilst using prehabilitation interventions to improve physiological resilience, patient-reported and cancer outcomes.

Malcolm is a core member of the NIHR Global Health Research Unit with an interest in global surgery and cancer outcomes. He is a selection committee member for NIHR RfPB Southeast and Central and is Surgical Specialty Lead at the Wessex CRN.
