Samuel M. Stavis (Fed)

Samuel M. Stavis is the Leader of the Nanostructure Fabrication and Measurement Group. He received a B.S.E. in Engineering Physics from the University of Michigan and a M.S. and Ph.D. in Applied Physics from Cornell University, where he was also a Postdoctoral Research Associate in Biological and Environmental Engineering. At Cornell, he performed early research in measuring fluorescence from single molecules in nanofluidic devices. Sam joined the NIST staff through a National Research Council Postdoctoral Research Associateship award. At NIST, he has advanced what is possible to make and measure at small scales. By developing and combining fabrication processes, device technologies, and microscopy methods, he has established new ways and limits of controlling and quantitating nanoscale systems. His research has diverse applications in manufacturing, healthcare, and the environment. Sam has received a Bronze Medal award, two Innovations in Measurement Science awards, a Strategic and Emerging Research Initiative award in support of the Circular Economy Program, and an Outstanding Authorship award from NIST.
