Hilary Browne | Advanced Research Assistant

Browne, Hilary

Hilary's work is based upon culturing, curating and whole genome sequencing of the human gut microbiota. Different culture conditions can target fastidious members or particular phenotypes. This growing culture collection will facilitate further studies into the functions and phenotypes that characterise the gut microbiota.

The majority of the human microbiota is still considered unculturable. While culture independent approaches have largely defined the role of the intestinal microbiota to date, genomic and phenotypic characterisation of individual members relies on culturing and archiving for future analysis. To acquire these fastidious bacteria we utilise anaerobic culturing facilities combined with targeted phenotypic culturing techniques. Whole genome sequencing and downstream computational analysis provides an understanding of the underlying genotypes. Beyond learning more about the members of this community - its constituents, the health benefits they provide to their host and how we acquire and transmit them, these bacteria will provide a resource to potentially develop therapeutics to treat diseases associated with the intestinal microbiota.
