Research Interests

My research focuses on vascular function and inflammation, NO bioavailability and vascular-ventricular interactions. I have a keen interest in identifying novel agents that may improve vascular health, as measured in vivo, in human models of health and disease.

We use well-described models to characterise this in our Department as well as more experimental approaches to stratify patients. These include forearm plethysmography, flow mediated dilatation and arterial stiffness as well as a range of haemodynamic and circulatory measurements. These biomarkers enable us to understand the mechanisms underlying the improvement or deterioration in vascular health in vivo from an NO bioavailability viewpoint, provide proof of concept of human physiology and pathophysiology and also help interrogate the role of various peptides and hormones in the regulation of vascular tone. The strength of these unique types of clinical physiological studies lies in their direct relevance to human biology, occasionally confirming pre-clinical models, but simultaneously providing relevance to human pathophysiology.

We are also interested in developing more novel approaches to understanding vascular pathophysiology using non-invasive imaging and bespoke technologies to understand angiogenesis. These techniques may be applied to human physiological studies and clinical trials of investigational medicinal products. This enables the translation of pre-clinical models of novel therapeutic agents into niche products differentiating an investigational medicinal product from existing therapies, or providing proof of mechanism in order to progress such a product through the stages of clinical drug development. For example, building on some seminal work performed by local collaborators, we have used FDG PET-CT in a novel experimental medicine study to understand the effects of a new therapeutic agent in altering the biology of atherosclerosis. We have applied similar techniques to assess existing therapies for patients with chronic inflammatory conditions, to understand if they possess off-target pharmacology which may improve outcomes as an inadvertent benefit of therapy. Along similar lines, we are aiming to understand how new drugs may disrupt vascular networks in the microcirculatory environment by examining the effects of such therapies on conjunctival vessels in collaboration with Dr Paul Meyer in the Department of Ophthalmology.
