is a Professor in the Department of Environmental Engineering Sciences at the University of Florida. After he completed his Ph.D. from the Department of Civil and Environmental Engineering at University of Cincinnati in 1996 he has taught and conducted research at the University of Cincinnati, Ohio USA; the Università della Calabria, Cosenza, Italia; Louisiana State University, Baton Rouge, Louisiana USA; and the University of Genova, Genova, Italia. His current interests include the interactions of hydrology, chemistry and control/treatment/reuse of rainfall-runoff and snowmelt; green materials and infrastructure systems in the urban environment, such as engineering permeable pavement systems; in-situ geoenvironmental systems for hydrologic and chemical cycling; soil modification, unit operations and processes for stormwater and wastewater, storm water TMDL analysis and sampling methods, adsorptive-filtration phenomena, control of metals and nutrients, anaerobic digestion, urban drainage systems and solidification/stabilization. His teaching interests include storm water system design, wastewater systems design, geotechnical and geoenvironmental engineering, environmental hydrology and urban hydrologic cycling.
