Biography

Erin Shanahan is a microbiologist at the University of Sydney, serving as a a'Beckett Research Fellow within the School of Life and Environmental Sciences. She leads the Microbiome Gut Health Group at the Charles Perkins Centre, where her research focuses on understanding the role of gut microbial communities in gut health, the development of colorectal cancer, and responses to cancer treatments. Erin completed her PhD in infectious diseases at the Centenary Institute in Sydney, concentrating on bacterial pathogenesis and vaccine development. Her research interest shifted towards gut microbiota during postdoctoral work at the University of Queensland and Princess Alexandra Hospital in Brisbane, where she developed novel methods to assess the microbiome and isolate gut bacteria from low-microbial load tissues. Currently, her research examines how dietary intake influences gut microbial communities and their interaction with local and systemic immunity, particularly in relation to colorectal cancer and cancer immunotherapy outcomes. Erin's academic background encompasses molecular microbiology, microbial ecology, and immunology, with a focus on the mechanisms through which gut microbes can promote health or drive disease. Recognizing that gut microbiota are essential for health, she investigates the impact of dietary factors on microbial communities and their functional properties, aiming to clarify their implications for gut health and disease risk.
