Environmental engineer named Distinguished Research Professor

As detailed in a paper he co-authored in the journal Science on the path for securing clean water, Dionysiou's work also emphasizes the need to consider the precautionary principle and eliminate, or at least minimize, pollution at the source. In addition, his research includes mechanistic aspects of removing the pollutants, evaluation of treatment efficiencies, and development and optimization of new treatment technologies. He has been a prolific researcher with over 600 peer-reviewed journal publications and over 60,000 citations, but he credits this outcome to the synergistic work between his students and collaborators. He values creativity, passion for scientific research, systematic work, and completion of assigned projects, theses, and dissertations. He always strives to learn new things when researching, gets excited when his students come up with new ideas, and is not afraid to take risks by venturing into new research areas. 

He serves in numerous research, educational, outreach committees, and leadership roles. As a testament to his contribution at the international level, he has been elected academician of the European Academy of Sciences and a fellow of four other professional societies (International Water Association, American Chemical Society, Royal Society of Chemistry, and Association of Environmental Engineering and Science Professors). He serves as a guest/visiting/honorary professor in nine international universities. He has organized numerous conferences, including symposia, to highlight the pioneering work of women in environmental engineering and science. Dionysiou received over 50 awards, including the ARCADIS Frontier in Research Award, the Outstanding Publication Award from the Association of Environmental Engineering and Science Professors, and the Sustainable Water Award from the Royal Society of Chemistry. He strives to provide opportunities and support his students by promoting their work for recognition and rewards. 

As a result, his students received over 130 university, state, national and international awards. In 2021, Dionysiou received the W. Wesley Eckenfelder Graduate Research Faculty Advisor Award for Outstanding Lifetime Achievements for Advancement of Environmental Protection for his mentor role.
