Director of the Pacific Center for Isotopic and Geochemical Research, Killam Professor at the University of British Columbia, Dominique Weis, is a leader in the innovative use of trace element and isotope geochemistry and is widely respected "for the elegance, precision, and impact of her geochemical studies of the Earth from large igneous provinces to the environment" (AGU Fellow citation). Her research aims to (1) determine the origin, source and pathways of mantle plumes (e.g., Hawaii, Galapagos), and their variations through time; (2) apply geochemical tools to resolve Indigenous-led questions about artifacts' origin, distribution and trade; and (3) improve our understanding of human impact, using biomonitors such as honey or salmon to trace metal distribution in the environment. Dr. Weis has published over 240 peer-reviewed articles, served on scientific editorial boards, and lectured in academic and public settings and policy committees for regulators and legislators. A graduate of ULB, Belgium, she is a 3-term Canadian Research Chair. She was elected AGU Fellow in 2010 and Geochemical Fellow in 2011 and was awarded the Canadian Federation of Earth Science Mentorship Medal in 2020. Dr. Weis also serves on scholarly or leadership committees for the American Geophysical Union, the Geochemical Society, and NSERC.
