Wenhao Sun, Dow Early Career Assistant Professor of Materials Science and Engineering at the University of Michigan, and Joonsoo Kim, a doctoral student of materials science and engineering in Professor Sun’s research group, show off dolomite rocks from their lab's collection. The two scientists have developed a theory that could finally explain a two-century-old puzzle surrounding dolomite's abundance on Earth.
