The Midwest Emerging Technologies Public Health and Safety Training (METPHAST) Program develops and disseminates web-based modules to educate and train a variety of learners about health and safety issues associated with emerging technologies [including nanotechnology]. This is a multi-institutional collaboration among the University of Minnesota School of Public Health, the University of Iowa College of Public Health, and Dakota County Technical College. With funding from the National Institute of Environmental Health Sciences Superfund Research Program, online courses have been developed to disseminate the identified critical areas for instruction.
