Dr Choudhary's main research work is based around mechanisms and treatments of hypoglycaemia unawareness, with a special interest in the psychology of patients with recurrent hypoglycaemia, and the changes in the brain that are associated with that seen on neuroimaging. 
He is also interested in the use of technology in diabetes, with a large clinical and research interest in the use of insulin pumps, continuous glucose monitoring and closed loop insulin delivery. 
He is also clinical lead for the islet transplant service at King's, and diabetes lead for the pancreas transplantation at Guy's Hospital.

Research interests


1]  Mechanisms and management of hypoglycaemia unawareness.

Previous work has included:

  • Epidemiology of hypoglycaemia
  • Pharmacological therapies to restore awareness
  • The use of technology to reduce hypoglycaemia
  • The use of neuro-imaging to understand the maladaptive changes that lead to impaired awareness of hypoglycaemia.


2] Use of technology in management of diabetes

Our group has been involved in a number of commercial and non-commercial studies looking at the use of insulin – pumps and continuous glucose monitoring systems in diabetes. This ranges from initial experimental work with closed loop system, to clinical studies of devices in specific populations.


3] B-cell replacement [Transplantation in Diabetes]

We are one of 6 UK islet transplantation centres and one of 2 Nationally funded islet isolation labs. We have ongoing research interests in optimising islet transplantation.
