PhD title: Inhibition of adipose tissue lipolysis during exercise to enhance the effectiveness of a walking programme to improve insulin sensitivity in people with pre-diabetes.

PhD start date: 14th November 2018

Project description: For my first project I will investigate GLUT4 translocation during a hyperinsulinemic-euglycemic clamp (HEC) to show that with high free fatty acid availability, GLUT4 translocation in skeletal muscle is impaired. My second study and third study will investigate whether a novel combined exercise and pharmacological intervention can improve insulin sensitivity and glycemic control in people with pre-diabetes.

Biography: I have been at LJMU for the past 7 years in the Sport and Exercise department, completing both my undergraduate degree followed by my MSc in Exercise Physiology. I am now in the final year of my PhD. Outside of academia, I enjoy running, and really good coffee.
