Interests

Teaching

I teach undergraduate courses on Water and Wastewater Treatment and Water and Sanitation in Developing Countries and graduate courses in Water Reuse, UV processes in environmental systems, and Water Sanitation and Hygiene. Other interests include water and wastewater treatment processes (physical, chemical, and biological), environmental aquatic chemistry, ecological environmental engineering, water treatment process laboratory.

Research

Research focuses on investigation of alternative disinfectants and advanced oxidation for water and wastewater treatment. Specifically, efficacy of UV irradiation for inactivation of persistent and emerging pathogens; and the investigation of advanced oxidation processes for the degradation of environmental pollutants of concern in clean and reclaimed water for reuse. Specific focus on small systems, point of use and sustainability of water and sanitation infrastructure in developing communities.
