Research Project: Chia-Chen’s work deals with bacterial colonization of point-of-use drinking water filters. Her project is to identify how the opportunistic pathogens from tap water would be removed by or enriched in PoU filters, and to assess the associated risk due to opportunistic pathogens and antibiotic resistance.
Research Project: Hollie aims to isolate and quantify the bacterium L. pneumophila from various households in Flint, Ecorse, and Genesee County, Michigan to better understand the distribution and risk factors of Legionnaire’s disease.
Research Interests: Biological nutrient removal, wastewater treatment process modeling.
Research Project: Avery’s work revolves around identifying underlying factors causing dispersed bacterial growth and membrane fouling at a regional wastewater plant, and establishing a framework for finding a long-term solution.

Research Interests: Leon's current scientific interests lie in better understanding transmission mechanisms for pathogens that exploit water and sanitation exposure pathways the community-wide effects of sanitation. His two aims are to show how sanitation improvements in one household can have positive impacts on its neighbors and to measure disease risk from exposure to untreated wastewater that is being used for irrigation of agricultural crops.
Research Interests: Environmental health and sanitation of water systems, leveraging engineering solutions to address environmental injustices and barriers to environmental equity.
Civil & Environmental Engineering
Research Project: Sara’s research focuses on applying modeling and control approaches to achieve system-wide objectives for a combined sewer and wastewater system. This includes developing a data-driven modeling toolchain to predict wet-weather impacts on sewer dynamics and simulating coordinated control decisions to operate distributed sewer assets, like pump stations and storage basins.
Research Project: Brett is in the startup phase for a lab-scale membrane aerated biofilm reactor that utilizes a partial nitritation/anammox biofilm.
Research Project: Nick is working on the INFEWS (Innovations at the Nexus of Food, Energy and Water Systems) project, handling further construction and maintenance of the GG Brown urine diversion system, as well as nutrient analysis in the lab. He is also continuing work on the point of use filter study, testing the effectiveness of an automatic flushing device on water quality and the lifespan of the filter itself.
