Understanding the biology of longevity and ageing using a nematode model
The nature of the biological mechanisms at the heart of the ageing process is one of the greatest unsolved mysteries in science. An ideal model organism in which to study ageing is the free-living nematode Caenorhabditis elegans. This species has well-developed genetics, its ~100 million base pair genome is fully sequenced, and its life span is a mere 2-3 weeks. Importantly, numerous mutations have been identified in C. elegans which alter the rate of ageing, with some mutants living up to 10-times longer than wild-type worms. By understanding ageing in a simple animal like C. elegans we hope to begin to unravel the mystery of human ageing, and the wide range of diseases that it causes, from cardiovascular disease and type II diabetes, to Alzheimer's disease and cancer.

A focus of current work in this laboratory is understanding the biological mechanisms that cause pathologies of ageing, and how such pathologies lead to mortality; and how reduced insulin/IGF-1 signalling and dietary restriction suppress ageing and increase lifespan. Other interests include the mechanisms of organismal death, sex differences in the biology of ageing, the role of the microbiome in ageing, evolutionary conservation of mechanisms of ageing, and bioethical implications of ageing research. Our work is largely funded by the European Union and the Wellcome Trust.
