Key Research Interests

Our overarching research interest is the role ion channels and receptors play in the cellular and molecular mechanisms that underlie cardiometabolic physiology and disease with an emphasis of blood vessels, adipose tissue and the peripheral nervous system.

Vascular pharmacology & physiology We are interested in the role of the peripheral nervous system in controlling human arterial and venous blood flow, in additional to the role of vascular endothelium in the mechanical detection of blood flow.

Adipose biology and dysfunction  We are interested in the role of efferent and afferent nervous innervation of human white adipose tissue and regulatory changes associated with metabolic disease. 

Receptor-ligand interactions and drug discovery We have an active programme to investigate novel molecules that allosterically modulate human P2X receptors (a family of ligand-gated ion channels). We are interested in the identification (via HTS) and molecular interaction of (in silico docking, receptor-ligand SAR) small molecules, natural products and antibodies with human P2X receptors.

Our research programme is generously funded by the British Heart Foundation, BBSRC, Merck and AstraZeneca.
