Virtual consultations:

I have been consultant in diabetes, endocrinology and general internal medicine at the Royal Infirmary of Edinburgh since 2018. I was awarded a PhD in the effects of diabetes on the liver in 2016 from the University of Edinburgh. I am a Fellow of the Royal College of Physicians of Edinburgh.

My current clinical practice encompasses a wide range of endocrine conditions including thyroid disorders (under and overactive thyroid disease), thyroid nodules, adrenal insufficiency, adrenal nodules, male hypogonadism (testosterone deficiency), calcium disorders, pituitary disorders such as pituitary hormone under or overproduction and I also lead the regional endocrine nodule and thyroid cancer service.

My clinical practice also includes all aspects of type 1 and type 2 diabetes care and cardiovascular risk management. I have a specific interest in the use of newer type 2 diabetes therapies, tailoring the approach to each patient to promote weight loss and reduce the risk of disease complications.
