My work largely centres around understanding the molecular and cellular events that are involved in beta-cell dedifferentiation in human diabetes. Emerging from recent rodent lineage tracing studies, this exciting field may change the approach we take towards targeted therapies in Patients with type two diabetes. Recently, we have demonstrated beta cell dedifferentiated phenotypes and possible alpha cell reprogramming in tissue and islets obtained from Patients with clinical type two diabetes.

01/03/2015- 28/02/2018 Diabetes UK PhD studentship (£92,460.00): Defining the role of dedifferentiation as a primary mechanism of beta-cell dysfunction in type-2 diabetes
Currently, I have funding from the Confidence in Concept (CiC) scheme to work in collaboration with a large diabetes Pharmaceutical company. We have developed a humanised in vitro model of beta-cell dedifferentiation which we are utilising as a drug screening platform for the discovery of novel, disease modifying therapeutics. In addition, using a gain- and loss- of function approach, I am also exploring the role that various transcription factors play in beta-cell dedifferentiation. Critically, we are able to understand the potential clinical relevance of these studies through examining postmortem tissue obtained from Patients with type 2 diabetes.
