Research Group: Biden
In ensuing years, Trevor's original group has developed into a Unit, but still continues to focus on the nexus between signalling, cellular function and the pathophysiology of diabetes, be it investigating the molecular mechanisms of insulin resistance, or pancreatic beta cell dysfunction. He believes that the team’s current projects - endoplasmic reticulum stress in beta cells, and the surprising re-emergence of PKC as a therapeutic target for diabetes, are some of the most exciting of his career.
