About Andrew

Associate Professor Andrew Holmes is a microbial ecologist affiliated with the School of Life and Environmental Sciences in the Faculty of Science at the University of Sydney. He is based at the Charles Perkins Centre, where he leads the Gut Microbiome Project Node. His research specializations encompass microbial ecology, bacteriology, infectious agents, microbial genetics, nutritional science, and clinical sciences. Holmes investigates the gut microbiome's dynamics in the context of human health, nutrition, metabolic diseases, and animal production. Notable areas include diet-microbiome interactions, macronutrient influences on microbial communities, and the microbiome's role in weight loss, immunotherapy outcomes, and metabolic responses. He has contributed to understanding how intestinal nitrogen availability controls diet-microbiome interactions and how macronutrients mediate functional relationships between hosts and microbes such as Wolbachia in Drosophila.
