Dionysios (Dion) D. Dionysiou

Dr. Dionysiou was born on the Island of Cyprus. He is currently a Herman Schneider Professor of Environmental Engineering and Distinguished Research Professor (STEM) at the University of Cincinnati (UC). He has served as a UNESCO co-Chair Professor on “Water Access and Sustainability”. He received a Diploma (B.S./M.S.) from the National Technical University of Athens, Greece, and an M.S. from Tufts University, both in Chemical Engineering. He received his Ph.D. degree in Environmental Engineering from the University of Cincinnati in 2001.

Dr. Dionysiou teaches courses on drinking water quality, treatment and reuse, advanced unit operations for water treatment, advanced oxidation technologies, and physical-chemical processes for water quality control. His research interests include (i) physical chemical processes for treatment of surface water, groundwater, industrial wastewater, and other types of polluted water, (ii) advanced oxidation technologies, (iii) UV and solar light-based remediation processes, (iv) treatment of contaminants of emerging concern, (v) remediation of Harmful Algal Blooms/cyanotoxins, (vi) removal of toxic metals, oxyanions, and other inorganic constituents from waters; valorization of precious metals, (vii) environmental catalysis and nanotechnology, (viii) (nano)interfacial phenomena in environmental systems, and (ix) water sustainability. He has industrial experience with W. R. Grace where he performed research on investigating environmental problems in masonry formulations and he is serving as consultant of several environmental companies in the field of environmental engineering.

Dr. Dionysiou is the author or co-author of over 630 refereed journal publications (received over 72,000 citations, H-index of 138; i10-index 578; Google Scholar), over 87 conference proceedings, 39 book chapter publications, 38 editorials, over 50 research reports, two patents (with one more patent pending), >220 plenary/keynote presentations and invited lectures, and more than 600 invited and regular conference presentations. Dr. Dionysiou has also edited seven books. He has trained over 160 graduate and undergraduate students, postdoctoral associates, and visiting scholars in his laboratories.
