“Our lab focuses on the molecular mechanisms underlying metabolic diseases and ageing. These morbidities have a profound impact, both medically and also social and economically.”
Animals typically live in close association with commensal and symbiotic microbes forming a single metabolic unit – the Holobiont. Recent studies have revealed that the status of gut microbiota can influence nutrition-related syndromes such as obesity and type-2 diabetes, and ageing. However, to-date we know very little about how such interactions are regulated.
We focus on understanding how these microbial communities determine human physiology, and if they can be targeted by drugs to improve human health and ageing. We developed a complementary pharmacological pipeline with the potential to unravel drug-diet-microbe-host interactions. For this purpose, we utilise two tractable genetic models: the bacterium E. coli and the nematode C. elegans, widely used for host-microbiome research.
We combine classical and advanced microbial genetics and high-throughput genomic/chemical approaches with targeted metabolomics at the holobiont level. This strategy will identify drugable mechanisms in bacteria (e.g. signalling/biochemical pathways) that alter microbial metabolite availability with the capacity to regulate host physiology.
