Associate Dean for Postgraduate Research, Faculty of Science (2019 - present)
Director of the Biomedical Research Centre, UEA (2015 - 2021)
As an early career scientist I trained in the laboratories of Professor David Beech FMedSci (Leeds) and Professor R. Alan North FRS (Manchester), and established an independent research group following the award of a prestigious BBSRC David Phillips Fellowship. We collaborate with clinicians at the Norfolk & Norwich University Hospital, partners in Pharmaceutical industry and other academic groups to tackle pressing and challenging projects. My expertise encompass pharmacological and physiological aspects of vascular and adipose tissues, and the biophysical and pharmacological properties of ligand- and voltgae-gated ion channels.

Key Research Interests and Expertise
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.
