Professional Interests

Dr.Vidic's teaching interests include water chemistry and physical/chemical processes in natural and engineered systems. His primary research interests are in the area of surface science and physical/chemical processes for water, wastewater, hazardous waste, and air treatment. His recent work focused on fundamental studies of molecular interactions on carbonaceous surfaces, control of mercury emissions from combustion processes by adsorption-based technologies, development of novel sorbents for elemental mercury uptake through industrial ecology, phytoremediation of arsenic-contaminated waters, novel disinfection methods for the control of pathogens in water distribution systems and membrane filtration for water purification.
