FACULTY

Biography

Dr. Anthony Chappaz earned his B.S. in Chemistry from the University of Grenoble Alpes, his M.S. in Chemistry and Microbiology of Water from the University of Poitiers and his Ph.D. in Geochemistry from the University of Quebec. Following his doctorate, he was awarded a prestigious Agouron Fellowship to join the University of California – Riverside as a postdoctoral researcher. Since 2011, he joined Central Michigan University where he currently works as a full professor of Molecular Geochemistry within the Dept. of Earth and Atmospheric Sciences. His research program is vast and deals with trace element across disciplines: Earth’s history, critical metals, food security, lakes, and medical applications. He acts also as the Director of the STARLAB, a state-of-the-art analytical facility that specializes in analyzing trace elements in geological, environmental, and engineered matrixes. Dr. Chappaz has been advocating for reinventing the Industry – Academic partnerships and was recently named the first Executive Director of the CMU Research Corporation – Innovation & Partnerships. He is also the CEO of a star-up company based on his academic research. Dr. Chappaz has an adjunct position within the Dept. of Earth Sciences at the University of Toronto.
