Assistant Professor, Civil Engineering, College of Engineering


Ph.D., Civil Engineering, Florida State University, 2019


Dr. Simeng Li joined the Department of Civil Engineeirng at Cal Poly Pomona as an Assistant Professor in August 2019. His area of research and teaching interests focus on environmental and water resources. Dr. Li obtained his Ph.D. in Civil Engineering from Florida State University in August 2019. At Florida State, he conducted his dissertation work with Professor Dr. Gang Chen, focusing on the fate and transport of nitrogen in agricultural fields. Dr. Li's peer-reviewed papers have been published in the Journal of Cleaner Production, Waste Management, Journal of Analytical and Applied Pyrolysis, and other scientific and engineering journals. He has also reviewed more than one hundred manuscripts for these journals and reviewed textbooks for the Cambridge University Press since 2017. Dr. Li is a member of the American Chemical Society, Water Environment Federation, and Association of Environmental Engineering and Science Professors.
