Dr. Matthew J. Kohn earned his Ph.D. in Geology from Rensselaer Polytechnic Institute in 1991. After a Post-Doctoral Fellowship studying stable isotope geochemistry at UW-Madison, and teaching positions at Northern Illinois University, University of South Carolina, and Washington State University, he joined the faculty at Boise State University in 2007. Dr. Kohn's research interests include the development and use of geochemical techniques to investigate orogenesis (including major element, trace element, stable isotope, and radiogenic isotope geochemistry); chemical and isotopic analysis of metamorphic minerals, climatic and physiological analysis of organic phosphates; stable isotope, electron microprobe, ion microprobe and ICP-MS analysis; geochronology; thermodynamics, kinetics and phase equilibria. Dr. Kohn is a prolific author and reviewer for many geology journals. His field work has taken him to many locations around the globe from New England to California, and from India and Argentina to the Swiss and Italian Alps.
