Aside from the National Institute of Health, other agencies in the federal government such as the Department of Defense (DOD), the Department of Energy (DOE), NASA, and the National Science Foundation (NSF) spend millions of dollars per year funding various research projects.  The areas of research include new weapons technologies, new forms of alternative energy, and cutting edge developments in the space program.  All types of research grants are prone to fraud including: submitting a false grant application, using grant money for other research projects or personal expenses, falsifying results, or simply overcharging for time.  Any improper use of federal research grants may cause the researchers to be liable under the FCA.
