Dan’s teaching interest lies in emphasizing the need to consolidate medical issues with practical considerations in veterinary medicine. Dan focuses on challenging students with real-life scenarios, emphasising difficulties unrelated to medical problems, such as communication issues, professional issues, and managing limited resources. Dan lectures on topics related to professionalism, emergency and critical care and clinical nutrition. Dan is the Year Leader for Year 4 of the BVetMed Programme and BVetMed Rotations (IMR) Director.
Dan’s primary clinical interests involve management of critically ill patients, including those requiring mechanical ventilation, renal replacement therapy (dialysis, plasmapharesis) and interventional nutrition. Clinical syndromes with altered haemostasis such as sepsis, acute pancreatitis, and multiple organ dysfunction are another major area of interest. Dan also directs the Nutritional Support Service at the Queen Mother Hospital for Animals, and the Veterinary Trauma Centre.
