- Key research
- Marine microbes (marine bacteria,viruses, and single-celled plants and animals) recycle nutrients and form the biomass at the base of the food chain that supports all higher animals. My studies look at factors effecting the distribution and abundance of marine microbes. These factors include the physical environment (oceanography), interactions between the microbes themselves (the ‘Microbial Loop’), and impacts such as ocean acidification and, in surface waters, enhanced UV-B radiation. I am also interested in microbial diversity and functionality in sediments, particularly in areas impacted by drilling, and the role microbes may play in sediment remediation following disturbance.
