Our research projects

In people living with type 2 diabetes, platelets in the blood are more likely to clot, putting them at a higher risk of heart attack than people without diabetes. Dr Allan is seeing whether an existing type 2 treatment, semaglutide, could also protect people against heart damage. This could improve people’s health and mean they need to take less medications, easing the day-to-day-burden of living with type 2 diabetes. 

Sometimes insulin can cause cells to multiply rather than bringing down blood sugar levels. This can increase the risk of some cancers in people with diabetes. Prof Nia Bryant wants to better understand how and why insulin can have this effect. With her PhD student, she will pinpoint the specific areas on cells that causes insulin to lower blood sugars and not to tell cells to multiply. In the future, this could help scientists develop new treatments for people with diabetes that aren’t linked with an increased risk of cancer.

Children born to mothers living with obesity or diabetes during pregnancy are more likely to develop heart problems. Dr Samuel Burden is investigating whether changes in the heart that start during childhood continue into adulthood, and whether health behaviours, like physical activity or diet, could help reduce this risk. This could help us find new ways to prevent generational links between diabetes and heart problems in offspring. 

Type 1 diabetes can affect anyone at any age, but it does not progress in the same way for everyone. We can identify people who are developing the condition, before symptoms appear. But we can't accurately predict when they will progress to 'full' type 1, when insulin is needed. For some people, progression through the early stages is rapid, while for others it can take many years.

Professor Gillespie and her PhD student will build on existing research to investigate the biological factors linked to these differences in progression. Their findings could help predict how quickly someone is likely to fully develop type 1 diabetes, and support the development of new ways to delay or prevent it.

Muscle damage is a common but under-studied complication of type 2 diabetes. It reduces mobility and can affect independence. Professor Lee Roberts will explore if a drug licensed to treat problems with how the body processes iron could help to improve muscle health and quality of life. This could improve our understanding of muscle damage in people with type 2 diabetes and provide us with better ways to treat it.

Polypharmacy is when people are prescribed multiple medications at the same time. It’s common in people with diabetes, and while it can be helpful in many ways, it can also throw up challenges. Professor David McAllister wants to shed more light on polypharmacy in people with diabetes. He’ll study health records and interview people with diabetes and healthcare professionals to understand their experiences. This clearer picture could help to develop approaches to reduce polypharmacy and its harm. 

Antidepressant drugs have been found to help lower blood sugar levels in people living with type 2 diabetes and depression. Dr Liu’s team want to explore whether the drugs can protect insulin-producing beta cells, and how they do this. In the future, this could help scientists to repurpose antidepressants to open the door to new ways to treat type 1 or type 2 diabetes. 

Type 3c diabetes develops because of damage to the pancreas. It often goes misdiagnosed and there’s no tailored treatment or care for people living with it. Professor James Shaw is testing existing drugs to see if they could help to repair the pancreas and boost insulin production. This research could pave the way for more effective treatments, helping those with type 3c diabetes better manage their blood sugar levels.
