Mary-Lou Tercier-Waeber, B.Sc, is currently Senior Researcher in the Analytical and Biophysical Environmental Chemistry (CABE) group at the University of Geneva (Switzerland). For the past 20 years, her work has focused on the development of new voltammetric sensors, mini/micro-integrated analytical systems, submersible probes and analytical techniques, and the application of these tools in laboratory, in-field andin situto study priority trace metal complexation, speciation and biogeochemical cycles to better understand the circulation, role and impact of trace metals in aquatic ecosystems. She has over 40 publications in international peer reviewed journals in Analytical Chemistry and Environmental Sciences, 3 invited book chapters, and 1 patent.
