Dr. Walker’s research focuses on understanding surface chemical processes in natural and engineered systems, with an emphasis on clean water. Current areas of research include: predicting the fate and transport of manufactured nanomaterials, cyanotoxins, and other “emerging” contaminants in groundwater, lakes, oceans, and water treatment plants; developing novel membrane treatment systems and membrane cleaning approaches; and the research and development of innovative, on-site wastewater treatment systems for removal of nitrogen. Dr. Walker has been funded by the National Science Foundation, US Environmental Protection Agency, United States Geological Survey, Department of Energy, National Oceanic and Atmospheric Association (through Sea Grant), and a variety of state agencies, industries, and other sources.
