Clarivate, a scientific and innovation analytics company, annually releases the list of researchers who have demonstrated significant and broad influence as reflected in the publication of multiple papers frequently cited by their peers during the last decade. These papers rank in the top 1% by citations for a field and publication year in the Web of Science citation index. 

Dionysiou was listed in the general engineering category as well as environment/ecology. He has more than 600 publications which have been cited a total of 60,000 times in other papers. He has several publications cited more than 1,000 times and many others cited more than 100 times.

Dionysiou conducted an extensive project to create a sensor that detect toxins in drinking water sources before the water enters treatment plants. He recently received funding from the National Science Foundation for research to further address the toxic chemicals released by harmful algal blooms in bodies of water. This research will evaluate and optimize a new treatment process that uses UV light with chlorine to break down cyanotoxins in water. Current treatments do not fully remove cyanotoxins.  

In addition, he recently has been funded by the Ohio Department of Higher Education to develop strategies for the removal of cyanobacteria cells from water reservoirs and phosphorous from source waters. In some other recent projects, he has developed strategies to break down difficult to degrade chemicals such as per- and polyfluoroalkyl substances (PFAS) in various water sources, as well as to remove emerging contaminants such as pharmaceuticals and personal care products in water supply sources.

UC research seeks to protect athletes from brain injuries

December 1, 2022

Former football players worry about the effects of concussions suffered during their playing careers and hope research from the University of Cincinnati will help them and future generations avoid the worst consequences of brain injuries. UC’s Office of Research hosted a panel discussion in the Flashpoint Series, “Brain Injuries in Sports: How we can help our athletes,” which addressed the effects of brain injuries and how research aims to develop solutions to protect athletes.
