A physicist who coauthored NIST guidance for evaluating measurement uncertainty with Barry N. Taylor. Their framework separates uncertainty estimates obtained statistically from repeated observations from estimates based on other information, then combines contributions into a standard uncertainty. This is useful when comparing a measured physical constant with a theoretical prediction: a corrected bias and the uncertainty remaining after correction are different quantities.[ref]
