Theme lead: Jeremy Tomlinson
Jeremy Tomlinson’s work tries to understand the mechanisms, in particular the role of steroid hormones that drive metabolic disease, including obesity, insulin resistance and non-alcoholic fatty liver disease. His work uses cell models as well as translational clinical studies to better understand the processes by which fat accumulates in the liver and to trial new and emerging treatments.

Sub-Theme Co-Lead: Leanne Hodson
Leanne Hodson is Associate Professor of Diabetes and Metabolism and a British Heart Foundation Senior Fellow. Leanne’s research focuses on the liver and its pivotal role in fat metabolism as it integrates endogenous and exogenous fatty acids (FAs). Perturbations in liver FA metabolism have the potential to impact widely on metabolic health. Accumulation liver fat underlies the spectrum of conditions known as non-alcoholic fatty liver disease (NAFLD) which is an important risk factor for cardiovascular disease and diabetes.

Key Researcher: Costas Christodoulides
Costas Christodoulides’s work focuses on understanding how obesity leads to the development of diabetes and cardiovascular diseases. Specifically, his research aims to understand the molecular and cellular mechanisms regulating adipocyte number (adipose tissue ‘expandability’) and distribution within the body; two key determinants of susceptibility to obesity-associated cardiometabolic diseases. To achieve this, he uses a combination of human genetic and physiological approaches, coupled with functional studies in human fat depot-specific cellular models
