Dr Li is a professor of Geosciences in the Geosciences Department. He served as the Chairperson of the department from 2009 to 2021. He earned his PhD in geology from the State University of New York at Buffalo. Dr Li’s speciality is in Earth materials and environmental application. His current research includes developing materials for contaminant removal from water. The most important projects conducted by Dr Li were evaluation of chromium and perchloroethylene removal using surfactant modified zeolite and zero-valent iron at a pilot-scale; Using ionic liquid modified zeolite as a permeable reactive wall to limit arsenic contamination of a freshwater lake at a pilot-scale; Assessment of carbon dioxide sequestrations in an abandoned oil reservoir; Interactions of Earth materials with pharmaceuticals and personal care products; Interactions of dyestuffs with Earth materials and their removal from water. He has published more than 220 peer-reviewed journal articles. Of the more than 200 are from UW- Parkside. He engaged undergraduate students for research-related activities from Geosciences, Biology, Chemistry, and Environmental Studies and as co-authors, many of these students published peer-reviewed journal articles since 1999. He is a guest editor for several journals. He earned UWP CRCA Award twice in 2001 and 2011. Teaching-wise, he taught many Geoscience course with practical applications such as Minerals and Rocks, Field Methods in Geology, Environmental Geology, Introduction to Geochemistry, Aqueous and Contaminant Geochemistry, etc., in addition to fundamental courses related to Geosciences, Environmental Studies, and Chemistry
