Current research projects in the Science Research & Engineering Program represent a cross section of the cutting edge research that is occurring in the Cleveland area, such as work on gene therapy, MEMS (microelectromechanical systems) nanotechnology, BioMEMS, and microelectrochemical sensor development, as well as research into cures for many life-threatening diseases. One project, called PEACE, addresses a real erosion problem in low earth orbit, and will fly in space twice, once as a short term exposure experiment aboard the space shuttle, and another time as a long term exposure experiment aboard the International Space Station. That version is in space now.
