Research Interests

My group studies the chromatin remodelling mechanisms that underlie V(D)J recombination and allelic exclusion of antigen receptor loci, in particular the immunoglobulin heavy and light chain loci. We have shown that large-scale non-coding RNA transcription (antisense and intergenic) precedes both D to J and V to DJ recombination at regions poised for recombination, and have proposed that this process opens up the chromatin to facilitiate stage-specific V(D)J recombination. We have developed RNA-FISH techniques to visualise primary transcription on individual Ig alleles in single cells. We are also interested in the nuclear organisation of V(D)J recombination, and in understanding events that predispose to generation of chromosomal translocations of the Ig loci and B cell lymphoma.
