Tom's teaching activities centre on post-graduate education of the Emergency and Critical Care Specialists-in-training, along with ad hoc teaching and seminars provided to other clinical departments. Tom's primary role in undergraduate teaching is that of acid base analysis, and he also has an active role in nurse education being the deputy module leader for systems based critical care nursing on the Diploma of Advanced Veterinary Nursing (ECC).
Tom's primary clinical interests involve extracorporeal therapies such as cardiopulmonary bypass and continuous renal replacement therapy (dialysis, therapeutic plasma exchange). From 2018 until 2024 he was the clinical lead for acute post-operative cardiothoracic critical care. Tom is a senior member of the extracorporeal therapies programme and has specific clinical interest in advanced blood gas and acid-base disorders, electrolyte disturbances, multiple organ dysfunction syndrome and mechanical ventilation. Tom strongly advocates the "book-to-bedside" approach of direct application of physiologic principles to the clinical patient especially in the context of transvascular fluid dynamics and the endothelial glycocalyx.
