Dr. Mike Scharf, O. Wayne Rollins/Orkin Chair in Molecular Physiology and Urban Entomology, Department of Entomology. Dr. Scharf earned his bachelor's degree in entomology, a master's in urban entomology and a doctorate in insect toxicology/urban entomology, all from Purdue. He comes to Purdue from the University of Florida, where he had been on the faculty since 2004. Dr. Scharf is interested in adaptations in insects that drive evolutionary divergence, particularly those with real-world significance in pest management. He has developed a nationally recognized program in molecular insect physiology that features toxicology, gene identification and cloning, development and metamorphosis, and cellulosics.
