George Ramsay is a Senior Lecturer in the Health Services Research Unit, having joined the unit in 2021. He is also a Consultant Colorectal and General Surgeon in Aberdeen Royal Infirmary. Before moving to HSRU, he was a SCREDS clinical lecturer in the Rowett Institute of the University of Aberdeen. His clinical training started in the University of Edinburgh where he undertook his undergraduate training, followed by his surgical training in the North and North East of Scotland. During his training, he took time out to undertake a PhD in Mucosal Immunology studying the lymphocytes in the small and large intestine that are key to maintaining health of these organs.

His current research interests are in describing and characterising Emergency General Surgery, assessing outcomes in colorectal cancer management and medical education.
