Dr Alexander Miras is currently a senior clinical lecturer and consultant in endocrinology at Imperial College London. He is interested in the mechanisms through which lifestyle interventions, pharmacotherapy, bariatric surgery and medical devices improve weight, metabolic control and diabetes-related microvascular complications.
