My research investigates the many ways in which hydrodynamics affect environmental systems, including sediment transport, water quality, and components of the food web. Numerical models and field observations are my tools of choice, and I enjoy developing open source software, hardware and data resources to support these approaches. Some visualizations of my work are on youtube:

• Microplastics as buoyant particles in San Francisco Bay. A particle tracking model simulating particles that sink, float, or remain neutral is used to understand how microplastic pollution is transported in the Bay and either retained or exported to the coastal ocean.
• Tidal currents in San Francisco Bay.
• Surface salinity in San Francisco Bay. This is a snapshot from an eXploratorium exhibit, demonstrating the movement of saltwater and freshwater in the Bay.
