The goal of my research is to ultimately enhance our capability of predict responses of marine ecosystems to long-term and abrupt changes in the environment. I am particularly interested in understanding the vulnerability of the coastal biome to environmental issues such as harmful algal blooms and hypoxic events, the frequency and magnitude of which are linked to both climate and anthropogenic forcing. Specifically, I seek to understand within the context of high-resolution simulations of Earth System Models 1) the key physical and biogeochemical processes underpinning these environmental issues and, 2) the associated time scales that determine not only productivity and community composition within the coastal systems, but also the rates of lateral material (e.g. carbon and nitrogen) transport between the land and open-ocean interface. These studies are aimed at addressing the impact of environmental changes on coastal ecosystem services and human well-being, the role that the coastal ocean plays in global carbon cycling, and how this role may change in the prospect of global climate change.
