My main interest is focused on how eukaryotic DNA is packaged and organised within the cell. In particular, I am interested in how the core histones are assembled into nucleosomes to create a platform for higher order chromatin structure. As many nuclear processes require access to the genome to exert their function, such as transcription, DNA replication & DNA repair, correct assembly and disassembly of chromatin structure is imperative for proper cellular function.

H3 & H4 chaperoning pathways

Key to the chromatin assembly process is a set of histone specific chaperoning proteins that govern histone folding, storage and incorporation into chromatin. These are very dynamic processes, with histones being incorporated into chromatin within minutes of being synthesised in the cytoplasm. During this time it is thought that histones are transferred between a number of different chaperoning and histone modifying proteins in a maturation process that produces deposition-competent histones.

I am interested in observing such transitions in living cells using the core histone H3 and H4 as models for chromatin assembly. In order to visualise and quantify such dynamic behaviour in living cells I am developing methods that interface synthetic biology and protein engineering tools with state of the art live cell imaging approaches.

It is hoped that being able to visualise these processes in real-time will broaden our understanding of one of the most fundament processes in chromatin biology.
