Bio

Dr. Zhao is currently Professor and Chair of the Civil, Construction, and Environmental Engineering. Before this post, Dr. Zhao was the Alumni Endowed Distinguished Professor of Environmental Engineering at Auburn University. He received his Ph.D. in Environmental Engineering from Lehigh University in 1998, and started his tenure at Auburn in 2001. Dr. Zhao is internationally recognized for his pioneering work in developing novel stabilized nanoparticles for in situ degradation of organic pollutants and immobilization of metals, metalloids and radionuclides in soil and water. Zhao’s group is also recognized for their pioneering work in developing adsorptive photocatalysts for destruction of persistent organic pollutants such as per- and polyfluoroalkyl substances (PFAS) in contaminated waters. In addition, the group made significant contributions in the transformation and environmental fate of spilled oil in seawater and coastal sediment and estuaries and in developing cost-effective technologies to control pollution of coastal ecosystems and the nearshore environment.

Dr. Zhao has served as PI or Co-PI for ~50 research projects totaling ~$9 million. He and co-workers have published more than 230 SCI-indexed journal papers, one textbook, 15 book chapters, and 250+ other publications. In addition, he has delivered 135+ invited or keynote presentations/lectures worldwide, and has been granted 7 U.S. patents. His work has been cited ~17,000 times with an h-Index of 66 according to the Google Scholar. He is included in both the Clarivate World’s Top 1% Scientists and the Stanford World’s Top 1% Most Cited Scientists.

He has served on numerous scientific review panels of various major funding agencies in the U.S. (NSF, EPA, SERDP/ESTCP) and worldwide. In addition, he has been serving as Editors for three journals: Water Environment Research, Frontiers of Environmental Science & Engineering, and Current Pollution Reports, and he is an editorial board member of three other international journals.

Dr. Zhao and his group have been recognized with numerous awards, including the 2021 Auburn University Creative Research and Scholarship Award, Auburn Engineering Council Endowed Distinguished Professorship, Huff Endowed Professorship, the 2021 Geosyntec Best Paper Award (with student), the ESPR 2019 Best Paper Award, the FESE 2020 Best Editor Award, and the Outstanding Oral Presentation Award (American Chemical Society, 2019), to name a few.
