I am a molecular pharmacologist specialising in research into the signal transduction mechanisms that connect events at the cell-surface (ligand-receptor binding) to altered cell responses in both health and disease. I have published >200 original research papers and a number of highly cited reviews (see Google Scholar: http://scholar.google.co.uk/citations?hl=en&user=TeVsJCkAAAAJ).
I have a degree in Biochemistry (BSc (Hons) University of Bath) and doctorate in metabolic regulation (DPhil University of Oxford). Following post-doctoral research into applying NMR spectroscopy to understand muscle bioenergetics I joined the University of Leicester initially as a Wellcome Trust-funded research lecturer and subsequently as Senior Lecturer Reader and Professor (Chair in 2003). I am presently Head of Department (since October 2017).
My research contributions have been recognised by the award of a fellowship (FBPhS 2016) by the British Pharmacological Society. I also hold a Fellowship (FHEA 2016) from Advance-HE.
My research has been supported by a number of funding bodies including the Wellcome Trust British Heart Foundation UKRI (MRC BBSRC) and the European Commission funders. I have been an academic partner in successful industrial collaborations (e.g. with GlaxoSmithKline). Present research projects include:
1. Understanding signal transduction and metabolism in astrocytes. How are metabolic flux-generating steps regulated by extracellular cues and can this new knowledge be used to target phenotypic alterations that occur in cancer (glioma/glioblastoma)? [in collaboration with Dr Paul Glynn]
2. Alterations to G protein-coupled receptor (GPCR) signalling brought about by G protein-coupled receptor kinases (GRKs) and arrestin proteins. With a focus on the cardiovascular system how does GRK-dependent phosphorylation of different GPCRs lead to arrestin recruitment and whether this causes a cessation of signalling (desensitization/internalization) or a second phase of signalling by the receptor (e.g. the formation of arrestin-dependent signalling scaffolds)? [in collaboration with Dr Jon Willets]

I have supervised 32 students to successful completion of PhDs as well as numerous other students undertaking lab-based research projects (MRes MSc iBSc undergraduate). I would be happy to supervise new doctoral students interested in pursuing research projects in the following areas:
1. Understanding signal transduction and metabolism differences in cancer and non-cancerous cells.
2. How do G protein-coupled receptor kinases (GRKs) and arrestin proteins regulate G protein-coupled receptor (GPCR) actions in health and disease?
I am a member of the Physiology Pharmacology and Neuroscience teaching and learning team which is responsible for delivery of Biological Sciences (Physiology and Pharmacology) Biological Sciences (Neuroscience) and Medical Bioscience (Medical Physiology degrees. I teach across all years of the School of Biological Sciences (SoBS) degrees and contribute to 4 modules including one that I convene. In addition I teach within Leicester Medical School (LMS) and offer research projects to SoBS (undergraduate and MSc/MRes)and LMS (iMSc) students.
