Each of our cells contains the same genome, the same set of instructions, but exhibit wildly different morphologies and functions. We are interested transcription factors, chromatin modifiers and non-coding RNAs regulate access to the genome to specify and maintain different cell types. Our research uses embryonic stem cells as a model for embryonic development and T helper cells as a model for adult cell differentiation and is underpinned by our expertise in genomics, bioinformatics and molecular biology methods.

1. The role of RNA in chromatin regulation
We and others have revealed links between non-coding RNAs and the polycomb group of chromatin modifying proteins. We are seeking to establish the molecular mechanisms and biological significance of polycomb-RNA interactions.
2. Transcriptional control of T helper cell specification
The transcription factors T-bet and GATA3 specify Th1 and Th2 lineages, respectively. We are using this system as a model for understanding how the interplay between antagonistic pairs of transcription factors leads to cell fate decisions.
3. Epigenetic disregulation in Cancer
Cancers exhibit abnormal patterns of chromatin modifications that may contribute to tumourigenesis by fixing cells in a normally transitory differentiation state. We are studying how mutations in polycomb proteins lead to changes to epiegentic state associated with cell transformation.
4. Viral control of host gene expression
Viruses seek to control cellular gene expression to establish a cellular environment conducive to replication and avoid the host anti-viral response. We are identifying the cellular genes directly targeted by viral transcription factors during infection.
