Centre for Microbiology and Environmental Systems Science

The Division of Microbial Ecology | DOME at the Centre for Microbiology and Environmental Systems Science | CeMESS is a team of microbiologists and molecular biologists. Our mission is to unravel the complexities of microbial life and its profound impact on our health and environment.
Our researchers explore the evolution, ecophysiology, interactions and functions of microbes across a broad range of systems. We apply cutting-edge methods, from 'omics analysis, to single-cell isotope probing, to microbial imaging, to computational community modelling.

Get to know our research by exploring our active projects and the researcher profiles of our principle investigators.

We are committed to nurturing the next generation of scientists, including undergraduate and doctoral programs, as well as intensive methods-based courses.

Our Facilities and Ressources include Joint Microbiome Facility, NanoSIMS, probeBase, and daime.
