Dr. Patrick Gilcrease joined the faculty in 2002 to lead the Biochemical Engineering initiative at SDSM&T. A native of western Kansas, Patrick earned his Bachelor of Science degree in Chemical and Petroleum-Refining Engineering from the Colorado School of Mines in 1987. After working for Dow Chemical as a process engineer for four years, he returned to graduate school, receiving both an M.S. and a Ph.D. in Chemical Engineering from Colorado State University. Prior to joining the SDSM&T faculty in 2002, he taught at the University of Wyoming for four years.
