Profile

Following a BA in Natural Science at Hertford College Oxford and a PhD in Medicine (Pathology) from Guy's Hospital Medical School, Steve Greenwald obtained a British Heart Foundation Junior Research Fellowship working on arterial elasticity in children. This was followed by a position as research assistant in the Pathology Department of The London Hospital Medical College. He has been on the academic staff of The Medical College since 1980 and obtained a personal chair in Cardiovascular Mechanics in 2001. Between 2002 and 2016 he was head of intercalated degrees and an Associate. He was elected as the Vice President of the International Society of Pathophysiology in 2006 and holds visiting professorships in Thailand and China.

Centre:  Cell Biology and Cutaneous Research.

Research

Research Interests:

The causes of cardiovascular disease are diverse, but during the last two decades, the importance of mechanical factors in their pathogenesis has become widely recognised. For instance, changing stiffness of the large arteries is a powerful prognostic indicator of mortality and morbidity for hypertension, stroke and coronary heart disease. Our research activities are aimed at a better understanding of the relationship between arterial composition, structure and mechanical function and range from mathematical modelling of the shear waves resulting from disturbed blood flow, through investigation of impaired vascular function in patients with diabetes and thalassaemia, to understanding how fatigue failure of elastin in adult life contributes to hypertension associated with impaired growth in-utero. On the applied side, recent work has been concerned with the development of novel methods for the measurement of arterial function including the activity of matrix metallo proteases, investigating the haemodynamic properties of novel stent/grafts and the non-invasive and indeed non-contact measurement of arterial stiffness and vascular endothelial function. These ideas are propagated to students undertaking the intercalated degree in experimental pathology as part of the teaching in the CV Pathophysiology module.
