>More information at: Session 16 - Advanced Oxidation Processes
At CEST2025, the Advanced Oxidation Processes (AOPs) session will be dedicated to the memory of Prof. Dionysios (Dion) D. Dionysiou (1968-2023) - a pioneer in environmental engineering, o global leader in water treatment technologies, and a valued member of the CEST Organizing and Scientific Committee for many years.
A few words about Prof. Dionysiou
Dionysios (Dion) Dionysiou was a visionary scientist, mentor & philanthropist, who believed that access to I safe drinking water should be a global right, regardless of geography, social status, or financial means. For nearly three decodes, he dedicated his career to advancing water purification & disinfection
technologies, particularly through the development of innovative advanced oxidation processes.
Prof. Dionysiou earned his Bachelor's degree in Chemical Engineering from the Notional Technical University of Athens (1991), followed by a Master's degree from Tufts University (1995) & a Ph.D. in Environmental Engineering from the University of Cincinnati (2000). He served for 23 years at the University of Cincinnati, mentoring students, faculty, and scholars worldwide. His research addressed a broad spectrum of topics, including:
- water treatment,
- advanced oxidation technologies,
- sustainable water processes,
- environmental nanotechnology, and
- removal of biological and chemical contaminants.
His 2023 publication in Water Journal reflects his extensive contributions to the field.
He authored over 600 peer-reviewed publications and delivered more than 600 invited talks in +50 countries. From 2018 to 2022, he was consistently recognized as o Highly Cited Researcher by Web of Science in Engineering, Environment & Ecology, and Chemistry. Prof. Dionysiou also held leadership roles in the ACS Division of Environmental Chemistry, supporting early-career, female, and international researchers.
He served as UNESCO Co-Choir Professor on "Water Access and Sustainability" (2013-2017) and received numerous honors, including the 2014 AEESP Frontier in Research Award, the 2017 AEESP Distinguished Service Award, and the 2022 Prince Sultan Bin Abdulaziz International Prize for Water (PSIPW) Creativity Prize, awarded jointly with his students.
