Overview
Research overview
I investigate the roles of secreted proteins in regulating the differentiation, survival and phenotype of developing vertebrate neurons. In particular, I am interested in the roles of these proteins in modulating the growth of axons and dendrites which establishes neural connectivity in the developing vertebrate nervous system. More recently, I have become engaged in research aiming to identify the mechanisms that underlie the degeneration of Substantia Nigra dopaminergic neuron axon terminals in the striatum, a process that precedes the motor symptoms of Parkinson’s disease.

Research
Research
I investigate how secreted proteins regulate neuronal differentiation, survival and the establishment of neural connections in the developing vertebrate nervous systems. In the last decade, I have become focussed on members of the TNF and TNF receptor superfamily’s, proteins that were originally characterised as immune modulators. It is becoming increasingly clear that many members of the TNFSF and TNFRSF play crucial roles in neural development, in particular in the establishment, maintenance and remodelling of neural connections. Techniques employed in my research group include: primary cell culture; fluorescent labelling and imaging of neuronal processes and an analysis of the length and complexity of axons and dendrites in vitro and in vivo; molecular techniques to analyse gene expression and intracellular signalling in neurons exposed to secreted proteins; transgenic approaches to determine the effects that modulating the expression of secreted proteins and their receptors has on developing neurons, both in vitro and in vivo.

Biography
I joined the School of Biosciences at Cardiff University as a Senior Lecturer in June 2004. Prior to taking up this position at Cardiff, I worked as a Senior Scientist at Rinat Neuroscience a biotech company situated in Palo Alto, California that was established in 2001, the year I joined the company. Before joining Rinat, I held a Royal Society University Fellowship and was working at the Royal Dick Vet School at Edinburgh University. The Fellowship was awarded in 1999 whilst I was a post-doc in the Department of Biology at St. Andrews University and I moved to Edinburgh in early 2000. I had arrived at St. Andrews University to take up my second post-doctoral position in 1996 after completing my first post-doc appointment in the Department of Molecular Pathology at University College, London from 1993-1996. Prior to this, I undertook a PhD in Molecular Neurobiology in the Department of Anatomy at St Georges Medical School, London between 1987 and 1992. I studied for a BSc (hons) degree in Biology at Southampton University between 1983-1986.
