Dr. Alicyn Rhoades specializes in polymer thermodynamics, with active research in polymer crystallization using fast-scanning calorimetry techniques. She also has active research projects focusing on polymer composite formulation as well as materials for additive manufacturing. She is also a graduate faculty member of the Materials Science and Engineering (MatSE) Department at Penn State University.

Dr. Rhoades received the Ph.D. in Polymer Science and Engineering (2006) from The University of Southern Mississippi with a graduate minor program in Commercializing Technology. She received her B.S. in Plastics Engineering Technology (2001) from Penn State Erie, The Behrend College. Prior to joining Penn State Behrend in August 2012, Dr. Rhoades was employed as Industrial Marketing Manager, Thermoplastic Urethanes, at Bayer MaterialScience LLC from 2011-2012 and as Innovation Manager from 2009-2011. From 2007-2009 she was Research Commercialization Project Manager at The Pennsylvania NanoMaterials Commercialization Center.
