Steven Grantham (Fed)

Steve Grantham received his Optical Science and Engineering Ph.D. from the University of Central Florida's Center for Research and Education in Optics and Lasers (CREOL). His graduate research involved the study and application of short pulse laser produced plasmas. He has been a beamline scientist at NIST’s SURF III since 1999.  He is currently working on the NIST’s EUV reflectometry, radiometry, and scatterometry projects at SURF III.
