I joined The University of Queensland in 1983, following positions at Griffith University and Monash University, and was appointed Senior Lecturer in the Department of Microbiology in 1995; overseas research has included periods in the laboratory of Professor James T Staley, University of Washington, the Laboratory of Prof. Mike Rout in the Department of Cellular and Molecular Biology, Rockefeller University, and the Department of Microbiology, Radboud University of Nijmegen.

Research in my laboratory is concerned with major questions in evolutionary microbiology, microbial cell biology and microbial ecology. It concentrates on the relevance of bacteria in divergent phyla such as Planctomycetes, Verrucomicrobia and Poribacteria to significant deep problems of biology such as the origin of the eukaryotic cell nucleus and eukaryotic cell skeletons, and in a second stream, on the diversity of the bacteria including planctomycetes and actinobacteria, of marine sponges and their relevance to natural product biodiscovery. Planctomycetes include bacteria such as the anammox planctomycetes, significant for environmental remediation and sustainability due to their ability to oxidize ammonia without the need for oxygen, and significant also for understanding the global nitrogen cycle as a major source of atmospheric nitrogen.
Planctomycete research – a window on evolution of the cell and cell biology
The planctomycete Gemmata obscuriglobus, which we have shown possesses a membrane-bounded nucleoid analogous to the interphase nucleus of eukaryote cells, is used as a model for study of planctomycete cell organization and its relevance to cell evolution, via ultrastructural and genomic approaches. We have recently made the major discovery of an endocytosis-like process in the bacterium G. obscuriglobus, a process previously thought to be restricted to eukaryotes. This process displays distinct molecular signatures of eukaryote cell biology, and its discovery has major implications for the understanding of the origin and evolution of the nucleus and endomembrane system of eukaryote cells. We are developing genetic systems for study of planctomycetes and approaches to characterizing the molecules underlying their cell biology via proteomics and genomics.
Sponge microbial community bacteria – a new resource for biodiscovery
In a connected effort to that on planctomycetes, we also study the diversity of bacteria associated with Great Barrier Reef marine sponges, with the aim of identifying microorganisms in these sponges possessing similar cell organization to that of plactomycetes. The bacteria of these sponges, including members of the novel actinobacterial genus Salinispora and their metagenome are being isolated and screened for genes responsible for polyketide antibiotic synthesis within the context of marine biotechnology and drug discovery. With Prof Nick Shaw of the School of Pharmacy and Dr John Hooper of Queensland Museum, we are exploring the diversity of Salinispora from sponges of the Great Barrier Reef and their potential for synthesis of diverse natural products including antibiotics and anti-cancer compounds and as a source of genes for natural product synthesis such as non-ribosomal peptide synthases. The anti-mycobacterial rifamycins and the anti-cancer staurosporines are two such compound classes we have detected in our cultures. We are also exploring the potential for planctomycetes to synthesize bioactive compounds via gene sequencing methods.
