He received a Dipl. Ingeniero in water resources from the Universidad Nacional del Litoral, Argentina, and an M.S. and a Ph.D. in civil engineering from the University of Minnesota. His two primary areas of research are sediment transport (e.g., particle-turbulence interaction, sediment erosion and resuspension by unsteady flows, turbidity currents, particle and pollutant transport and transformation) and environmental hydrodynamics (e.g., turbulence effects on aquatic life, vegetation-flow interaction, density currents, and boundary-layer flows in-
