Our research interest has focused on mapping epigenetic deregulation in cancer, focusing on prostate cancer.  We have made significant contributions to the discovery of Long Range Epigenetic deregulation in cancer, including regional gene silencing and activation.  A focus of the group has been to understand the mechanism underlying aberrant DNA methylation. 

Early work on the GSTP1 gene in prostate cancer elucidated the ‘trigger’ of aberrant DNA methylation in prostate cancer  cells and we went on to  elucidate the intimate relationship between gene expression, DNA hypermethylation and chromatin modifications in prostate cancer cells. Our current research interest is to understand the role of the epigenetic modifier MBD2 in the spread of DNA methylation and its role in aberrant DNA methylation in cancer.

The group has also played an integral role in developing new epigenetic technologies, including ongoing optimization of bisulphite sequencing for DNA methylation analysis which is the “gold standard” method for DNA methylation analysis, chromatin immunoprecipitation, RNA-seq, and the development of genome-wide analysis of methylated DNA and chromatin modifications by next-generation sequencing. Recently the ChIP-bis approach was developed enabling the direct interrogation of chromatin modifications and DNA methylation.
