The National Aeronautics and Space Administration (NASA) awarded a $499,846 grant to Assistant Professor Casey DeRoo for research related to Rapid Electron Beam Lithography Patterning for Customized Reflection Gratings. 

The research is intended to develop techniques for customizing reflection gratings through electron beam lithography. As the prime contractor, DeRoo’s research team at the University of Iowa will leverage its expertise in nanofabrication and optics to support NASA's ongoing research into advanced optical components and instrumentation.
