Research Interests:
I am interested in the application of biological processes for the treatment of water, wastewater, and hazardous waste. One of my main areas of specialization within biological processes is biofilms, which are microbial communities immobilized on solid surfaces. My biofilms research program aims to enhance understanding of the structure and function of biofilms in engineered and natural systems, to develop or improve treatment processes that use biofilms, and to develop strategies for controlling biofilm growth on surfaces when biofilms are not desired. In addition, I am interested in studying the composition and reactivity of aquatic natural organic matter (NOM) with emphasis on the impacts of NOM on drinking water quality and treatment. Finally, my research group is involved in developing and applying innovative methods to analyze hydrophilic organic chemicals (e.g., haloacetic acids) in aqueous solutions and in studying the fate of these chemicals in aquatic systems (e.g., water distribution systems).
