William Peck teaches mineralogy and petrology, and manages Colgate's Stable Isotope Laboratory. His research program focuses on the magmatism, metamorphism, and ore deposits of the Grenville Province, a billion-year-old exposure of mid-crustal rocks that stretches from Labrador to the Adirondack Mountains of New York. 

B.S. Beloit College, 1994; M.S. and Ph.D. University of Wisconsin, 1996 and 2000.
