Research interests include:
- The morphology, physiology, ecology and molecular phylogeny of cyanobacteria especially open ocean nitrogen fixers.
- The biology of chemoautotrophic nitrifying bacteria, aerobic nitrogen fixing bacteria and cellulolytic bacteria.
- Symbioses between bacterial species and between bacteria and eukaryotic organisms.
- Ecology of cyanophages.
- Mechanisms responsible for microzooflagellate feeding patterns.
