Dr. Roper examines electrodynamics in nanomaterials and bio/chemical systems for biomedicine, sustainable energy, and optoelectronics.  Particular examples are light-active nanostructured metamaterials (e.g., nanoplamonics) for detectors, microarrays, and NEMS; nanolithography and electron microscopy for sensors, optodes, and sensorimotor circuits; graphene and stanene-based 2D materials; and functional membranes for biofuels and fuel cells.  Dr. Roper has developed processes for cell culture, fermentation, biorecovery and analysis of polysaccharide, protein, DNA and adenoviral-vectored antigens at Merck & Co. (West Point, PA), extraction of photodynamic cancer therapeutics at Frontier Scientific, Inc. (Logan, UT), and virus binding methods for Millipore Corp (Billerica, MA).  His research has led to 45+ peer reviewed publications and proceedings, 4 Patents, 6 patent applications, 1 viral and 3 bacterial vaccine products, 6 process documents, and 130+ presentations and process equipment designs.   He has advised 3 post-docs, 4 PhD graduates, 6 MS graduates, and 80+ undergraduates in his academic group and has directed research of 2000+ B.S. to Ph.D. level engineers and scientists in over 20 years in government, academe, industry, and small business.  He holds memberships in Tau Beta Pi, ACS, AIChE, ASEE, AVS, and IEEE. He is an invited Member of the Arkansas Academy of Science and Fellow of the American Institute for Medical and Biological Engineering (AIMBE).  Dr. Roper currently serves as Program Director in the Engineering, Education, and Centers Division of the Engineering Directorate at the National Science Foundation.
