Research Interests

• Hydrodynamics of the coastal ocean, estuaries, and lakes.
• Lateral dynamics in estuaries with complex topography, and their influence on mixing.
• The dynamics of stratification and baroclinic transport.
• Estimation of bottom roughness, bottom shear stress, and sediment resuspension in wave-dominated environments.
• Interaction between aquatic vegetation and hydrodynamics.
