Water and the Environment

My primary field of research is the development of water and wastewater (municipal and industrial) treatment technologies to enable non-potable and potable reuse of impaired water. Specific areas of research include membrane filtration and desalination processes, direct potable reuse, advanced biological treatment systems, data science integration in water systems, (renewable)energy-water systems, and decision support tools for selection and optimization of water treatment systems.
