My main lines of research are:
- To exploit the use of transgenic mouse models to determine the critical molecular events which contribute to the initiation and progression of tumourigenesis (primarily within the intestine and liver)
- To investigate the importance of the genes Cbx3 and HMGB1 in intestinal homeostasis and tumourigenesis
- To determine the epigenetic consequences of altered gestational diet, and ascertain the significance of these on lifetime tumour risk
- To investigate the alternative roles of APC (Adenomatous polyposis coli) which contribute to tumourigenesis but are independent to APC's role regulating Wnt signalling
I have worked as a postdoctoral research associate within the group of Prof. Alan Clarke in Cardiff school of Biosciences since Oct 2002. My research utilises a number of clinically relevant, transgenic mouse models of cancer (principally intestinal and liver cancer) with the aim of clarifying or establishing some of the critical molecular events that contribute to the initiation, establishment and progression of cancer.
Prior to moving to Cardiff, I worked within the group of Prof Wolf Reik at the Babraham Institute, Cambridge, under whose supervision I also completed a PhD (awarded in Sept 2000). Here my research focused on understanding the epigenetic regulation of the imprinted locus on mouse distal chromosome 7 (a chromosome region involved in foetal overgrowth and cancer susceptibility) and I characterised the molecular basis of, and consequential imprinted phenotype of, the novel radiation-induced mouse mutation Minute (Mnt).
Preceding this I graduated from the University of Bath with a BSc honours degree in Applied Biology in 1996. During my degree course I completed a year's research in The Institute of Medical Genetics, Cardiff, where I characterised the inheritance of multiple genetic markers within families of Rett syndrome patients (a childhood neurodevelopmental disorder) and refined the genetic map of this disease.
My objective now is to develop my own research group using the expertise I have obtained from working at Cambridge and Cardiff.

Mouse models of human diseases facilitate an understanding of the mechanisms that contribute to the initiation, establishment and progression of diseases such as cancer in human.
I am interested in transcriptional regulation, and my research aims to identify genes and pathways that are critical in the initiation and progression of cancer, utilising multiple clinically relevant, transgenic mouse models of intestinal cancer to achieve this.
The (APC) tumour suppressor protein is well characterised as a key regulator of Wnt signalling, and elevation of the levels of b-catenin is a known consequence of loss of APC function. Mutations in the APC gene are associated with both familial and sporadic colon cancer pathogenesis and links with other cancers including hepatocellular carcinoma and renal cancer are reported.
The conditional deletion of Apc in the adult intestine or liver quickly results in the neoplasm. Transcriptome analysis using affymetrix microarrays has identified a number of transcripts that are differentially regulated following the conditional loss of Apc in this system and the data generated has been used to establish some of the critical molecular events that contribute to the initiation and progression of tumourigenesis (e.g. Sansom et al 2004+2007, Reed et al 2004, 2006+2008).
Two potentially clinically relevant biomarkers and drug targets for colorectal cancer, Cbx3 and Hmgb1, form the current focus of my independent research. Cbx3 encodes the protein Hp1gamma which plays a critical role in chromatin organisation and gene expression, while Hmgb1 also bind chromatin and facilitates the binding of other proteins to DNA.
My first involvement in public engagement was through the Beacons for Wales Researchers in Residence scheme 2009, but I have regularly undertaken a range of activities since. Some (e.g, the Beacons for Wales $1000 genome project in Park Prison, Bridgend, the "Learn about Life" events in Cardiff School of Biosciences or Biology Rocks at Cardiff Museum) have been pre-organised by others, while other activities I have initiated and organised myself (e.g. school visits to Goytre Fawr Primary school, Archdeacon John Lewis Primary school, Pencoed Comprehensive, or the Lab in an "ice-cream Van activities in collaboration with Tenovus). Furthermore, I have successfully obtained funding to support my outreach activities, and have supported others to do the same.
I have developed a highly successful interactive workshop demonstrating the power of the polymerase chain reaction and its application in cancer research. This 3 hour workshop has been frequently used, including for visiting pre-GCSE pupils who were participating in a Hands-On Science Summer Residential course, and for teacher CPD training. It has since been developed into a "loan box" for schools to undertake PCR within the classroom. More details can be found here http://sites.cardiff.ac.uk/cube/resources/loan-boxes/
