Samuel M. Stavis

Samuel M. Stavis is a Project Leader in the Nanofabrication Research Group. He received a B.S.E. in Engineering Physics from the University of Michigan and a Ph.D. in Applied Physics from Cornell University, where he was also a Postdoctoral Research Associate in Biological and Environmental Engineering. At Cornell, he combined nanofluidic devices and optical microscopy to measure single nanoparticles and biomolecules. In 2007, Sam joined the NIST staff through a National Research Council (NRC) Research Associateship award. In the NIST Physical Measurement Laboratory, he engineered complex nanofluidic devices, advanced single molecule metrology, and developed microfluidic nanomanufacturing processes. In 2012, Sam joined the CNST, where he leads several projects combining nanoscale particles, device technologies, and optical measurements for applications in manufacturing and healthcare. Sam has received two Innovations in Measurement Science awards for the most creative ideas to advance the measurement capabilities of NIST.
