Professor Hay graduated with BSc (Hons) and MB ChB degrees from Glasgow University in 1973. He trained in internal medicine and endocrinology during 1974-8 in Glasgow Royal Infirmary, where he obtained his MRCP (UK) and a PhD degree. He became a Senior Fellow in Endocrinology during 1978-81 at the Mayo Clinic, but returned to Edinburgh University during 1981-83 as the Sir Stanley Davidson Lecturer in Medicine. Since 1983 he has been a Consultant in Endocrinology at Mayo and, since 1989, a Professor of Medicine. In 2006, he became the Dr RF Emslander Professor of Endocrine Research and in 2014, a Mayo Distinguished Clinician Awardee. Since 1984 his research interest has been in the prediction of outcome and the impact of initial management in >4500 papillary thyroid cancer (PTC) patients treated at Mayo during 1936-2015. He defined the AGES and MACIS prognostic scoring systems, has long advocated a selective role for radioiodine remnant ablation in PTC, and has at Mayo pioneered ethanol ablation as a safe and cost-effective outpatient treatment option for PTC patients with persistent neck nodal metastases and selected patients with cT1N0M0 papillary micro-carcinomas.
