Current Focus of Research:

• Bioenvironmental Engineering: Development of biological engineering processes for environmental applications.
• Examples include biological fluidized bed processes for surface and ground water decontaminations and sequencing batch reactor processes for nitrogen removal.
• Biological Nitrogen Removal: Nitrogen removal via biological nitrification/denitrification mechanisms.
• Examples include nitrogen removal of amines and biofilm nitrification/denitrification kinetics.
• Environmental Systems Modeling: Surface and ground water modeling, time series analysis of water and wastewater treatment facilities, and kinetic modeling of biodegradation processes.
