Weston Tew is an expert in the areas of thermal and electrical metrology. He has experience in precision electrical measurements, low temperature thermometry, noise thermometry, non-metal fixed points, and industrial thermometry and is an author of more than 70 papers on these subjects. Dr. Tew is a member the International Electrotechnical Commission, Working Group 5 on Temperature Sensors of the subcommittee 65B. He is also a member of: the ASTM International Committee E20 on Temperature Measurement; The Institute of Electrical and Electronic Engineers; and the American Physical Society. He has been a staff physicist in the NIST Process Measurements Division and the Sensor Science Division since 1993 where he is responsible for cryogenic resistance thermometer calibrations and maintenance of the ITS-90 below 84 K. His research interests are in temperature standards, resistance thermometry, Johnson noise thermometry, fixed points, and condensed-matter physics.
