Dr Cohen was appointed as consultant in endocrinology/diabetes in 2006. His research focused on the role of gut hormones in the regulation of food intake.

He has a special interest in the management of obesity in the context of type 2 diabetes and has clinical expertise in the management of hyponatraemia.
