I obtained a BSc in biomedical science from the University of Hull in 2001 and a PhD from Newcastle University in 2004. My interest in diabetes research continued during post-doc positions in the Diabetes Research Group at Newcastle University and during a travel fellowship at the University of Michigan, USA in 2007 (funded by EMBO/EFSD). In 2008 I was awarded the RD Lawrence Fellowship from Diabetes UK followed by the Newcastle University Research Fellowship in 2014.

My overarching research aim is to understand the mechanisms underlying the impairment in function and survival of pancreatic beta-cells in type 2 diabetes, cells with a critical role in regulating blood glucose homeostasis. I am particularly interested in how glucose sensing impacts on both beta-cell function and survival. My research falls into two main research areas: i) delineating the pathways mediating cell survival. vs death in type 2 diabetes, with a particular focus on autophagy; ii) identifying mechanisms for preserving the metabolic function of beta-cells. These areas are particularly relevant given the loss of beta-cell function and increased cell death evident in type 2 diabetes.
i) Role for autophagy in regulating beta-cell survival – aim is to delineate the complex interplay between apoptosis and autophagy in regulating beta-cell death and to understand how a current therapeutic target for type 2 diabetes (GLP-1) alters this crosstalk.
ii) Impact of glucose sensing on beta-cell autophagy - aim is to determine how glucose sensing impacts on autophagy in the pancreatic beta-cell under conditions mimicking type 2 diabetes.
iii) Understanding the role of cell connectivity in preserving the pancreatic beta-cell phenotype - aim is to identify the role of cell connectivity in preserving appropriate glucose-sensing by the pancreatic beta-cells.
