Leon J. Tilley


Professor Tilley joined the chemistry department in 1996 after completing his Ph.D. from Indiana University. He earned B. A.'s in Chemistry and Russian Language from Grinnell College in 1990.

His Ph. D. research involved conductometric rate-constant, isotope effect, and NMR product studies of gamma- and delta-silyl substituted carbocations, as well as software design for a bipolar pulsed conductance instrument. He also spent the summer of 2000 as an Adjunct Assistant Professor at Northeastern University and the summer of 2001 as a Visiting Investigator at the Woods Hole Oceanographic Institute. He is actively engaged in undergraduate research at Stonehill College, and has had numerous SURE and chemical research students working with him on a variety of projects.

He also teaches a variety of courses ranging from General Chemistry with a forensic theme to Organic Chemistry to Energy and the Environment. He is also interested in mineralogy and is an avid mineral collector.
