Teaching and Research Interests

Professor Dionysiou performs research in the fields of (i) Advanced oxidation technologies for water treatment, (ii) drinking water treatment and purification, (iii) physicochemical phenomena on particle-water interfaces, (iv) transition-metal oxidation and reverse electron transfer reactions, (v) the use of ionic liquids in environmental applications, (vi) destruction of biological toxins in water, and (vii) environmental nanotechnology (fundamental, fate, transport, and applications of nanomaterials).  At the University of Cincinnati, Professor Dionysiou teaches graduate courses in the fields of (i) Advanced Unit Operations for the Treatment of Drinking Water and Wastewater, (ii) Physical-Chemical Processes for Water Quality Control, and (iii) Advanced Oxidation Technologies and Nanotechnologies. He also teaches a graduate level laboratory course on Unit Operations and Process Monitoring for the Treatment of Polluted Water and Air and an undergraduate course in Environmental Engineering Fundamentals and Process Design.
