Research

My research group uses the budding yeast Saccharomyces cerevisiae and the nematode worm, Caenhorrhabitis elegans as model organisms in which to study how transcription, non-coding RNAs, higher order structures in chromatin, and histone modifications influence the response to changes in nutrient availability, metabolic state and ageing. Caloric restriction is known to increase lifespan in a wide range of organisms, including yeast, and may ameliorate the effects of age-related diseases but the mechanism involved are poorly understood.

Yeast and worms offer powerful tools for dissecting the pathways that allow cells to switch from active growth into a long-lived quiescent state. We use bioinformatics, 3C analysis, RNA-FISH, ChIP-seq, RNA-seq, nascent transcript mapping and most standard wet techniques. In addition, we produce models of cellular events such as gene expression and metabolic cycles in collaboration with physicists and mathematicians.
