Brief Bio: Steve, pictured above right, is a na(t)ive Texan. He received a B.S. from Stephen F. Austin University (like he needed more). After working two summers for the Forest Service in New Mexico and unable to find a real job, he got his Masters at University of Arkansas and his Ph.D. at the University of Georgia. Forest Health Protection, as part of their goal to employ the best and brightest, hired him anyway in 1991. He worked in the Pineville, LA field office until a decision was made to station an entomologist in Texas, and the other field office personnel unanimously voted to ship him out. Rumors of a romantic link with Rene Russo are unsubstantiated.
Professional Responsibilities: Provides expertise, training, and guidance on forest insect pest problems for Federal lands in Texas and Oklahoma, as well as other states in Region 8 and anyone within earshot. His main projects include the development of semiochemicals as tools for southern pine beetle suppression, biological control of an exotic mealybug in the PRC, and examining beetle diversity on the National Forest in Texas.
