About the Principle Investigator
Dr. Tiezheng Tong is currently a tenured Associate Professor at the School of Sustainable Engineering and the Built Environment (SSEBE), Arizona State University (ASU). He was a tenured Associate Professor at the Department of Civil and Environmental Engineering, Colorado State University (CSU). He completed a postdoc position in the Department of Chemical and Environmental Engineering at Yale University and received his Ph.D. degree in Civil and Environmental Engineering from Northwestern University. Prior to his Ph.D. study, he graduated from Beijing Normal University (with the highest honor) and Tsinghua University with B.S. and M.S. degrees, respectively, both of which are in Environmental Engineering. He has published nearly 80 peer-reviewed journal articles, which have been cited by >6,000 times globally with an H-index of 38. He is the recipient of many academic and professional awards, including the Super Reviewer Award from Environmental Science & Technology (2024), the James J. Morgan Early Career Award from American Chemical Society (honorable mention, 2024), the George T. Abell Outstanding Early-Career Faculty Award and Faculty Award for Excellence in Research from CSU (2023), the CAPEES/UCEEF Early Career Award from Chinese-American Professors in Environmental Engineering and Science (2023), the CAREER Award from National Science Foundation (2022), the 40 under 40 Award from American Academy of Environmental Engineers and Scientists (2022), ACS ES&T Engineering Best Paper Award (2022), the Young Membrane Scientist Award from North American Membrane Society (2020), a Student Award from Sustainable Nanotechnology Organization (2013), and Environmental Chemistry Graduate Student Award from American Chemistry Society (2012). He is currently an editorial board member of Journal of Membrane Science. His current research interests include (1) developing novel materials and processes to achieve circular water economy, (2) understanding and mitigating mineral scaling in membrane desalination, and (3) elucidating mechanisms of solute transport across selective membranes for water purification and resource recovery.
