David L. Duewer (Fed)

Dave is a chemical metrologist with particular expertise in chemometrics, experimental design, exploratory data analysis, graphical communications, interlaboratory comparisons, measurement uncertainty, and quality assurance/control. He is an advocate for R&D at interfaces of chemistry, biology, and measurement science. His current interests include better approaches to the: evaluation of chemical purity, demonstration of comparability among reference materials that nominally deliver the same measurands, and summarization of chemical data that have defined measurement uncertainties.
