Dr. Mengyan Li joins NJIT in 2015 from Rice University, where he is a postdoctoral researcher in the Department of Civil and Environmental Engineering specializing in environmental microbiology and biotechnology. Dr. Li develops water remediation techniques that deploy microorganisms to biodegrade organic pollutants of emerging global concern. He also researches interdisciplinary methods for improving urban water treatment technologies, including the use of nanotechnology to disinfect supplies contaminated with pathogens. To assess the microbial activity in remediation and treatment processes, he has developed genetic forensic tools, such as a novel biomarker test to evaluate the biodegradation of 1,4-dioxane, a groundwater contaminant. That work won him the Honor Award in the Excellence in Environmental Engineering and Science competition held by the American Academy of Environmental Engineers and Scientists. His ultimate research goal is to advance our knowledge on applied microbiology and molecular biotechnology and develop innovative techniques to mitigate and address environmental issues related to water and energy development. Beyond research, he has extensive experience and passion on educating undergraduate and graduate students and teaching courses on topics of environmental biology and microbiology.

EvSc 622 Bioremediation


My primary research interest is oriented to uncover novel biodegradation metabolisms and biotransformation pathways for emerging organic contaminants (e.g., 1,4-dioxane) and develop accordant genetic forensic tools to facilitate the assessment of microbiological activities in the environment. By incorporating modern biomolecular techniques and analytical instruments, my research is also expanded to cover from fundamental understanding of microorganisms and populations involved in natural and engineered systems of environmental relevance to technology innovation applicable for areas, such as sustainable water/wastewater treatment, bioenergy generation, biocorrosion prevention, and pathogen control. The central goal of my research is to advance current bioremediation and water treatment technologies using state-of-art molecular biological techniques to promote their performance and cost-efficiency.
