About this position
Johns Hopkins University’s Whiting School of Engineering is seeking a postdoctoral researcher for a NIST Professional Research Experience (PREP) collaboration in precision measurement of thermophysical quantities. The work is based in Gaithersburg, Maryland, and is centered on precision optical interferometry as a common measurement principle.
The researcher may contribute to several complementary research directions. One is the development of a cryogenic gas thermometer using refractive-index gas thermometry and a Fabry–Perot cavity resonator filled with helium, targeting measurements from 4 K to 303 K. Another is an air-based dilatometer using displacement interferometry and a linear-slide translation stage to measure the thermal expansion coefficient of materials relevant to dimensional metrology. A third direction uses a Faraday balance to measure the magnetic susceptibility of gases, including helium, neon, argon, and nitrogen, with the aim of resolving discrepancies between historic measurements and recent ab initio calculations.
The postdoctoral researcher will conduct research and development in precision interferometry and its application to thermophysical measurement. Activities include instrumentation of optical, electrical, and mechanical apparatus; control automation; instrument control; Python-based data acquisition, data curation, and analysis; and dissemination of results through journal publications and conference presentations. The research environment connects Johns Hopkins University with NIST laboratory research through the PREP program.
