Biography
Dr. Liyuan (Joanna) Hou is an assistant professor in the Utah Water Research Laboratory and the Biological Engineering Department. She also serves as an adjunct professor in the Civil and Environmental Engineering Department. She dedicates herself to researching applied environmental microbiology to monitor, minimize, or valorize contaminants and wastes.
Teaching Interests
Emerging Contaminants, Environmental Microbiology, Wastewater Engineering, Biodegradation, Bioremediation, Resource Recovery
Research Interests
Her research focuses on investigating and utilizing functional microbial communities to promote water quality and resource recovery in engineered and natural systems. In her research, she applies various methodologies such as genome sequencing, metabolic engineering, and metabolite analysis in the engineering aspect to understand how the contaminants interact with microbes to enhance the removal or valorization of contaminants. Her research interests fall under two themes: (1) exploring the interactions between microbes and multi-contaminants to track the transport, source, and driver of multiple pollutants in urban wastewater; and (2) understanding the interactions like biodegradation mechanisms of pollutants to minimize and valorize waste using microbes.
