A physicist associated with quantitative measurement and the evaluation of measurement uncertainty. With Chris E. Kuyatt, he wrote NIST guidance that separates uncertainty evaluated statistically from uncertainty evaluated using other information, then expresses both on a common standard uncertainty scale. This allows repeated readings, instrument specifications and other contributions to be combined into an explicit measurement uncertainty budget; correcting an estimated systematic error does not eliminate uncertainty in that correction.^[ref]
