Dean Johnston started at Otterbein in 1995 where he teaches courses in Introductory and Inorganic Chemistry.

Dean received his undergraduate education at the College of Wooster where he majored in Chemistry. He earned a Ph.D. in Inorganic Chemistry at Northwestern University working with Duward Shriver and continued his studies conducting post-doctoral work with H. Holden Thorp at the University of North Carolina at Chapel Hill.

Dean’s primary research interests are in synthetic inorganic chemistry and the photophysical properties of metal cluster systems. His research with undergraduate students has been supported by Research Corporation, the Petroleum Research Fund, and the National Science Foundation. Dean has also received funding to develop online resources for teaching molecular symmetry and to incorporate structural chemistry into the undergraduate chemistry curriculum.
