Why do our bodies decline as we grow old? Why does ageing cause disease? Can we slow ageing or even reverse it? The answer to these questions underlies nearly all non-communicable disease process. The past two decades have seen an explosion in understanding the biology of ageing. By tackling these questions, we aim to develop medicines that may one day prevent and/or treat diseases of old age, with a single therapy. Our ultimate goal is to allow people to live healthier, disease-free lives.
We focus on genes (e.g. sirtuins) and small molecules (e.g. NAD+ agonists) that mimic exercise and calorie restriction, a diet that slows the pace of ageing in animals. We use mouse models to test genes and small molecules for their ability to protect against common age-related diseases such as cancer, heart disease, Alzheimer’s disease, cardiovascular disease, infertility and type II diabetes. We also look at strategies to slow or reverse the pace of accelerated ageing that affects cancer survivors, who suffer the long-lasting side effects of chemotherapy treatment.
At the cellular level we study cellular metabolism, mitochondrial function, neuroprotection, cellular senescence and transposon activity. Expertise in the lab ranges from enzymology and biochemistry, using model systems including C. elegans, rodents and cell-based studies.
