John A. Kramar (Fed)

Dr. John Kramar is Deputy Division Chief of the Microsystems and Nanotechnology Division of the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology (NIST). He earned a B.S. in Chemistry from Abilene Christian University and a Ph.D. in Chemistry from the California Institute of Technology, where he studied the morphology and electronic structure of molybdenum disulfide using scanning tunneling microscopy and spectroscopy. John came to NIST through a National Research Council Postdoctoral Research Associateship award. At NIST, he joined and later led the Molecular Measuring Machine project for realizing the meter and measuring artifacts with atomic resolution and accuracy over a 50 mm by 50 mm area. John was also a key member of the NIST electrostatic force balance project for realizing the unit of mass at the milligram level. His current research interests include nanoparticle size and distribution standards and reference measurements and the development of instrumentation for precision length metrology at both meter- and micrometer-scale distances. John has been the recipient of four Department of Commerce Medal awards for his research accomplishments: one Bronze, two Silver and one Gold.
