I graduated from Edinburgh University in 2000 and became a Member of the Royal College of Physicians in 2003. Later that year, I joined the North of Scotland training programme as a Specialist Registrar in Geriatric Medicine and General Internal Medicine. In 2006, I joined the University of Aberdeen as Clinical Lecturer in Elderly Medicine.

I was a Consultant Geriatrician with NHS Grampian from 2008 to 2018, before joining the General Medicine Department at Aberdeen Royal Infirmary, returning to Geriatric Medicine in 2023. I have held numerous roles in postgraduate medical training, including Training Programme Director for Core Medical Training and Geriatric Medicine and serving as Associate Postgraduate Dean from 2015-2017.  

I was awarded an NRS Career Researcher Fellowship in 2012. Having previous held roles of Honorary Senior Lecturer and Honorary Reader, I was awarded an Honorary Chair in 2024.

Research Overview

I am interested in all aspects of health and disease in old age. My chief interests are hyponatraemia in older people and clinical pharmacology in old age. More recently, I have been working on COVID-19 therapy trials, and leading on vaccine trials. I have also researched polypharmacy, whole body vibration exercise, vascular ageing and cognitive ageing. I run clinical trials in older people but have wide experience in epidemiological and mechanistic studies, as well as systematic reviews.



Current Research

I am the Aberdeen Principal Investigator for the NOVAVAX, MODERNA P-305 (omicron), Medicago, BiCARB, K-SWAY, LACE, RAINDROP and SENATOR randomised controlled trials.

I have an ongoing interest in hyponatraemia, most recently investigating the causes of hyponatraemia after head injury.

I also led Wave 4 of the Aberdeen 1936 Birth Cohort (ABC36) Study, a longitudinal cohort study of  cognitive ageing.


I have supervised numerous undergraduate and postgraduate students from medical elective students to PhD candidates.
