The University of Aberdeen c/o Ageing Clinical & Experimental Research, University of Aberdeen, Room 1:128, Polwarth Building, Aberdeen AB25 2ZD United Kingdom


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. I have held numerous roles in postgraduate medical training, inclduing 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 Research Fellowship in April 2012.


Research Interests

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. 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 epidmeiological and mechanistic studies, as well as systematic reviews.



Current Research

I am the Aberdeen Principal Investigator for the 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.
