The George Washington University, in collaboration with the NIST Fundamental Thermodynamics Group, is seeking a highly motivated Research Associate for the NIST Professional Research Experience (PREP) program. This position offers the opportunity to engage in advanced metrological research aimed at establishing a new, higher-accuracy pressure scale using pneumatic piston gauges. Key research areas include characterizing piston gauges to minimize uncertainty in effective area, calibrating pressure transducers and gauges across a wide pressure range, and performing data and uncertainty analysis for high-precision measurements. The ideal candidate will have a Ph.D. (preferred), or a Bachelor's or Master's degree in Physics or a related STEM field, with experience in pressure, vacuum, dimensional, and/or temperature metrology. Proficiency in Python programming for data analysis is required. U.S. citizenship is strongly preferred. This role is ideal for those passionate about advancing measurement science and reducing uncertainty in pressure standards. For more information and to apply, visit the provided application link.
