Raymond A. Pearson received a B.S. degree in chemistry from the University of New Hampshire and a Ph.D. degree in materials science and engineering from the University of Michigan. He joined the Materials Science and Engineering Department at Lehigh University, Bethlehem, PA in August of 1990. In 2010, Ray became a Fellow of the Society of Plastics Engineers and in 2018 he received the Award for Excellence in Adhesion Science from the Adhesion Society. Ray’s research interests include all aspects of processing, deformation, yield, and fracture of polymers with a focus on adhesion and interfacial issues. Notable research accomplishments include the elucidation of toughening mechanisms in rubber-modified and silica-filled epoxies. Recent efforts are focused on the mechanical behavior of nanoblends and nanocomposites as well as 3D printing materials (for FFF and SLS).
