Cornelius F. (Neil) Ivory earned his BS in Chemical Engineering at the University of Notre Dame, his PhD at Princeton University followed by a year as a USRA Visiting Scientist in the Bioseparations group at NASA's Marshall Space Flight Center. In 1987 he found his home in the Voiland School of Chemical Engineering and Bioengineering at Washington State University where his research group specializes in multi-dimensional electrofocusing in microchannels, nanochannels and gradient monoliths.
Dr. Ivory is Full Professor in the Voiland School of Chemical Engineering and Bioengineering, Associate Director of the NIH Predoctoral Training Program in Protein Biotechnology at Washington State University and Senior Fellow in the Biomedical Engineering Center at the University of New Mexico. He has served as National Program Chair for the American Chemical Society (3 years) and as Councilor for the American Electrophoresis Society (6 years) as well as organizing various symposia and/or sessions for those societies and others, organizing and/or serving on various proposal review panels, editorial boards and technical workshops. Dr. Ivory has more than 80 refereed publications, 5 patents awarded and several more patents pending.
