Academic career After receiving his PhD from the California Institute of Technology in 1990, Blum began his academic career as an assistant professor of Earth Sciences at Dartmouth College, where he was promoted to Associate and then Full Professor. In 1999, Blum accepted a faculty position at the University of Michigan as the John D. MacArthur Professor. From 2000 to 2006, Blum was the chair of the Geological Sciences Department. In 2010, Blum received an Arthur F. Thurnau professorship for his achievements in undergraduate teaching, and in 2015, Blum was awarded the Jerry F. Keeler distinguished professorship for his excellence in research. the Sloan Foundation, the National Science Foundation, the University of Alaska, and Case Western Reserve. the Geochemical Society (2010), the American Association for the Advancement of Science (2010), and the Geological Society of America (2005).
