D. Keith Roper is Associate Director of Microelectronics-Photonics Graduate Program, Professor of Chemical Engineering, and holds the Charles W. Oxford Endowed Professorship of Emerging Technologies at the University of Arkansas. He is Associate Editor for IEEE Transactions on Nanotechnology.  He is a Member of the National Academies of Science, Engineering, and Mathematics Committee for Continuous Manufacturing for Modernization of Pharmaceutical Production. He served as NSF Program Director and Program Leader for the Engineering Research Centers and the Network for Computational Nanotechnology from 2012-2016. He is a Fellow of the American Institute for Medical and Biological Engineering and a member of the Arkansas Academy of Science. His research examining bioinspired electrodynamic functionality of nano-, bio-, and meta-materials has received recognition from DOE, EPA, and NSF and has been featured by SPIE Newsroom, R&D Mag, and over 40 other media outlets. He partners with leaders in academia, industry, and government to translate discovery to marketable innovations in biotech/biopharma, chemicals, optoelectronics, and energy. From 1994-2000 he developed processes for cell culture, fermentation, recovery, and analysis of protein, nucleic acid, bacterial polysaccharide, and adenoviral-vectored antigens at Merck & Co. From 1996-2008, he was instrumental in bringing three transgenes, 24 vaccine antigens and one anti-cancer compound, to human clinical trials and/or to market. He has developed novel bioprocess equipment for mixing and filtration. He has authored or coauthored more than 88 technical articles and published proceedings, 81 invited lectures, 136 conference presentations, two textbooks, 6 federal solicitations and dear colleague letters, two book chapters, three U.S. patents, one E.P. patent, and seven U.S. patent applications.  His Ph.D. is from the University of Wisconsin–Madison. He is active in ACS, AIChE, AIMBE, ASEE, IBE, IEEE, SPIE, and Tau Beta Pi.
