Tiezheng Tong

Dr. Tiezheng Tong is currently an Associate Professor at the Department of Civil and Environmental Engineering, Colorado State University (CSU). He joined CSU in 2017 after completing a postdoc position in the Department of Chemical and Environmental Engineering at Yale University. He 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 is the leading author or co-author of over 70 peer-reviewed journal articles, which have been cited by more than 5,000 times globally with an H-index of 37. He is the recipient of several academic and professional awards, including the James J. Morgan Early Career Award (honorable mention, 2024), the George T. Abell Outstanding Early-Career Faculty Award and Faculty Award for Excellence in Research from CSU, 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), American Chemistry Society 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). His current research interests include (1) achieving energy-efficient treatment of hypersaline brines for circular water economy, (2) elucidating fundamental phenomena at the water-membrane interface, and (3) applying data-driven approaches to promote water sustainability.
