Dr. Tinkham graduated with a B.Sc. in Geology from Rocky Mountain College (Montana), a M.Sc. in Geology from the University of Illinois, and a Ph.D. in Geology from the University of Alabama.  He came to Canada after the completion of his Ph.D. for postdoctoral positions at the University of Calgary. In 2005, Dr. Tinkham joined Laurentian University where he teaches metamorphic petrology and field schools.

His research is in the broad field of metamorphic geology, where he specializes in the application of thermodynamic calculations to investigate metamorphic processes and the pressure-temperature-composition evolution of rocks during metamorphism. This work is applied to rocks to decipher zoning and modification of metamorphosed hydrothermal alteration zones associated with ore deposits, metal mobility during metamorphism, partial melting of high-grade metamorphic rocks, and orogenic processes.
