Lisa uses numerical models and field observations to understand how coupled physical-biological processes influence (1) the food web base (phytoplankton), (2) water quality, (3) inter-habitat connectivity, and (4) the ways in which aquatic ecosystem functions and services may shift in future decades in response to changes in climate, management, or physical configuration. In particular, she studies interactions between environmental parameters and processes such as hydrodynamic transport, light availability, filter feeding by consumers, and bathymetry and their influence on biomass and productivity of phytoplankton. Her focus tends to be on tidal systems, although some of her work applies to rivers and lakes as well. She thinks of herself as an "Ecohydrodynamicist", but some of her friends like to call her things like "Hydro-phydamicist" (which she doesn't mind).
