Profile

For enquiries, please contact - iicd-om-operational@sheffield.ac.uk

I am a clinician scientist motivated by the needs of people living with diabetes.

I developed a passion for research during my intercalated BSc in the Medical Sciences with Haematology at Imperial College London. I completed my undergraduate training at Newcastle Medical School graduating with distinction and overall honours (distinction in all clinical undergraduate examinations and the Goyder Memorial Scholarship awarded to the best final year student).

I then undertook seamless clinical-academic training, first as an Academic Foundation Trainee in Endocrinology at the University of Bristol before moving to Sheffield as a NIHR Academic Clinical Fellow in Diabetes and Endocrinology. This led to a Medical Research Council (MRC) Clinical Research Training Fellowship to pursue a PhD at the University of Sheffield. Following this, I completed specialty training in Diabetes and Endocrinology in Sheffield as an NIHR Academic Clinical Lecturer.

I am currently a Senior Clinical Lecturer and an Honorary  Consultant Physician at the University of Sheffield and Sheffield Teaching Hospitals. My clinical interests are in managing problematic hypoglycaemia and the use of novel technologies in managing type 1 and type 2 diabetes.

.

Research interests

I am interested in exploring mechanisms whereby hypoglycaemia might lead to progression of atherosclerosis and mortality, helping to explain why intensive glucose control in patients with type 2 diabetes has failed to reduce macrovascular disease. 

Importantly, in addition to further dissection of mechanisms that underpin the relationship between hypoglycaemia and atherosclerosis, I want to conduct research to come up with novel therapeutic options that are urgently needed to mitigate the risk hypoglycaemia poses on the cardiovascular system in those with diabetes.

I am also interested in clinical research which employs use of novel diabetes technologies in treating problematic hypoglycaemia.
