Emeritus Professor Gerald Tannock

Research interests:

Gut microbiota (microbiome)

Current research:


Gut microbiota (microbiome).
Professor Gerald Tannock has researched the bacterial community inhabiting the gut of humans and other animals for more than forty years. The research has resulted in numerous publications, including two monographs, the most recent of which was Understanding the Gut Microbiota published in 2017 by John Wiley & Sons. He was a James Cook Research Fellow (Royal Society of New Zealand), inaugural Director of the University of Otago Research Theme Microbiome Otago, and a Principal Investigator of the Riddett Centre for Research Excellence. He continues to contribute to the scientific literature, and is a member of the Editorial Board of Applied and Environmental Microbiology (American Society for Microbiology).
