My research has focused on the effects of ultraviolet radiation on marine and aquatic bacterioplankton. The approach has been multidisciplinary including microbial ecology, oceanography, molecular biology and photobiology. Studies have been conducted in diverse environments ranging from coral reefs, the Mediterranean Sea, and temperate lakes. A significant amount of work has focused on the effects of ozone depletion on marine bacteria in Antarctica.
More recently my lab has also become interested in patterns of microbial community structure (microbial biogeography). Finally, while we have spent many years looking at the inhibitory effects of sunlight on bacterioplankton growth, we are now also investigating patterns of the stimulation of bacteria by visible light, or photoheterotrophy.
