Craig Liddicoat is an Adjunct Senior Fellow in the School of Public Health at the University of Adelaide. Craig's research interests include environmental microbiomes, spatial epidemiology, and developing knowledge of beneficial connections between human health and exposure to biodiverse vegetation-soil systems. In particular, the role that exposure to (and loss of) biodiverse green space may play in developing immune fitness, mental health and predisposition to both infectious and non-infectious diseases.
My research is exploring connections between environments, their microbial communities (microbiota), and the potential for human health benefits from nature-contact. The notion of a real biological (microbiota-mediated) connection between humans and their environments, and potential benefits for immune training and regulation from exposure to biodiversity (and associated microbial diversity), has originated from immunologists and medical researchers. However, this represents a large multidisciplinary field of research. My research has objectives to:
- help bridge the gap between environmental science, ecology and human health.
- investigate if there is support for possible health benefits from exposure to biodiversity in large existing environmental and public health datasets.
- build knowledge of biological (microbiota-based) connections between environments and exposed populations.
- help inform new cost-effective nature-based public health interventions.
