Molecular Epidemiology and Cardiology
Heart disease is the leading caurse of death globally, olthough major transitions in the spectrum of heart disease have occurred over time. The end-stage of all heart diseases - heart failure - results from insufficient cardiac output for the demands of the body at normal filling pressures. A plethora of biochemical changes have been described in the failing heart, but the molecular mechanisms remain poorly understood and carry potential therapeutic implications. An increasingly important form of heart failure is the non-ischemic form of cardiomyopathy seen in diabetes patients.
This research group seeks to improve understanding of the pathophysiology of heart disease, identify novel therapeutic targets and facilitate precision medicine in cardiovascular medicine. To this end, we leverage big data analysis and model-based experiments drawing on methods from genetic epidemiology, proteomics, metabolomics, functional genomics and population sciences. We have a particular interest in the pathways leading up to end-stage heart failure, diabetes cardiomyopathy, and in the pathobiology of the transplanted heart.
