Juris Meija is a research officer at the National Research Council Canada working in the area of chemical metrology and certified reference material development. He received his B.S. degree from the University of Latvia in 2001. He pursued his Ph.D. studies with Professor Joseph A. Caruso at the University of Cincinnati (USA) where he focused on the analysis of selenium metabolism in selenium accumulating plants for efficient ways to clean contaminated soil.
Today his principal focus is on mathematical modelling and data analysis in analytical chemistry, where he explores the reliability of chemical measurements and designs new approaches of experimental designs which enable more trustworthy measurements. Juris is also a recognized expert in isotope ratio measurements with recognized work on many elements including silicon, mercury, germanium, iridium, and osmium. In the intersection of these two areas, he develops mathematical frameworks for novel isotope-based quantitation techniques.
Juris serves as the Chair of the IUPAC Commission on Isotopic Abundances and Atomic Weights (2014-present) and is also IUPAC delegate to the Joint Committee for Guides in Metrology, Working Group 1: Guide to the Expression of Uncertainty in Measurement (GUM), and has been actively involved in many recent international activities such as the redefinition of the mole or naming of the new chemical elements. Since 2009 he is the Editor of Springer-Nature Analytical and Bioanalytical Chemistry’s column Analytical Challenge which aims at increased public appreciation and understanding of analytical chemistry.
