I am a Professor of Cardiovascular & Metabolic Sciences

BSc (Hons) Chemistry  at University of Wales Institute of Science & Technology (Awarded a 3 month scholarship to undertake research at Bucknell University, Pennsylvania, USA).

PhD (MRC studentship) in Biochemistry at  Imperial College of Science, Technology and Medicine, University of London (PhD supervisor Professor Howard Morris, FRS)

5 years working in the pharmceutical industry after which time I re-entered academia taking up a postdoctoral position at UMIST in the Department of Biomolecular Sciences. I was subsequently awarded a 5 year British Heart Foundation Basic Science Lectureship, which was then renewed for a further 5 years.   Upon the merger of UMIST with the Victoria Univeristy of Manchester to form the University of Manchester I transferred into the Cardiovascular Group in the School of Medicine.

Shortly after joining the Cardiovascular Group  I was promoted to Senior Lecturer, then Reader and more recently to Professor of Cardiovascular & Metabolic Sciences

STRUCTURAL AND MOLECULAR BIOLOGY OF HEART FAILURE in OBESITY & DIABETES

More than a third of the world's population are considered overweight or obese. Obesity is a risk factor for the development of type 2 diabetes (T2DM); more than half of all deaths in T2DM are attributed to cardiovascular complications. The rise in obesity/T2DM is also linked to the increased number of heart failure cases and in particular the phenotype, Heart Failure with Persevered Ejection fraction (HFpEF) a condition which is generally recalcitrant to current treatments. A hallmark of both obesity and diabetes is metabolic dysfunction associated with progressive pump failure. 

My group is investigating the biological, structural and molecular remodelling that leads to impaired cardiac energetics, aberrant lipid metabolism and reduced contractile function in models of obesity and diabetes. Projects are focused upon identifying pathological changes that occur in the early stages of disease to develop new strategies for preventing heart failure progression.

We are employing a multi-disciplinary approach combining state-of-the–art imaging techniques spanning 3D electron microscopy, confocal microscopy and live-cell imaging. These imaging modalities are complemented by biochemistry, proteomics, cell and molecular biology techniques ranging from single protein studies to whole cell functional analyses. 

Key research areas include themes around the development of dysfunctional cardiac metabolism, the intersection with inflammation (immunometabolics - https://www.bmh.manchester.ac.uk/research/domains/infection-immunity-inflammation-repair/immunology/cardiovascular-immunology/) with a particular interest in mitochondrial remodelling. We are also investigating the effects of hyperlipidemia on myocardial structure-function.

Our recent work has identified that in the early stages of diabetes there is a shift towards cardiac fatty acid metabolism leading to energy inefficiencies, with the accumulation of damaged mitochondria. We are now exploring the underlying mechanisms with the aims to identify new therapeutic agents.
