My lab’s research is focused on phytoplankton as model organisms to address questions related to water, climate and energy. We use quantitative and experimental approaches to elucidate the importance of biotic and abiotic factors influencing phytoplankton dynamics (community composition, physiology, ecology) in both field and laboratory-settings. One of the greatest challenges facing the world today is ensuring an adequate supply and quality of water to meet rapidly increasing human needs whilst securing the continued health of our waterways. The goal of much of the lab’s research is to understand and predict interactions between water systems, climate change, land use and ecosystem function and services in estuaries and coasts. Studies are performed at a level of spatial and temporal resolution to allow for extrapolation to other regions, and to ultimately develop and/or feed predictive models. One of the emerging issues for the 21st century is the fate and transport of engineered nanoparticles (ENPs) to the environment. By investigating ENPs which have trace metal cores, we have transitioned from investigating metals as nutritional components of phytoplankton to work on the toxicity of metals. Phytoplankton are directly and indirectly impacted by ENPs, and there is an increased potential for bioaccumulation and biomagnification of some metals to higher trophic levels. Because of their potential to alter biogeochemical cycles including the C and N cycle, this will continue to be an active area of future studies; as will be understanding the potential phytoplankton protective and detoxifying mechanisms.
