Scott Tanner is a Canadian scientist and entrepreneur renowned for inventing mass cytometry and co-founding DVS Sciences in 2004, which commercialized the technology and was later acquired by Fluidigm. Born in St. Catharines, Ontario, he earned his BSc and PhD in chemistry from York University, where he also competed as a nationally ranked gymnast before an injury turned him to marathon running. After a 25-year career at SCIEX developing mass spectrometry products, he became a professor at the University of Toronto and led DVS Sciences as its president and CEO. His research includes developing the DRC collision/reaction cell and the CyTOF instrument, alongside detecting dioxins and chemical agents. Tanner holds 22 US patents, has published over 74 peer-reviewed articles, and has received numerous honors, including the 2020 Lifetime Achievement Award in Plasma Spectrochemistry and the 2019 HUPO Award.
