Dr. Cristelle Portet, postdoctoral researcher in the Department of Materials Science and Engineering, was presented with the prestigious Delegation Generale pour l'Armement (French Army, DGA) Prize from the French Minister of Research and the French Minister of Defense at a ceremony held in Paris in January. Each year, the DGA awards up to 300 research grants to support Ph.D. candidates (similar to National Defense Science and Engineering Graduate Fellowships in the U.S.). One recipient out of the 300 is selected by the Ministry of Science for the DGA Prize, which honors the researcher whose study has shown the best outcome over a three year period.
DGA Prize winners are selected based on their achievements and the importance of the research problem they address. Dr. Portet wrote her Ph.D. thesis on improving the energy and power performance of supercapacitors, tiny but powerful electrical energy storage devices used in hybrid cars, back-up power supplies, and many other applications.
Dr. Portet conducted her Ph.D. study at Paul Sabatier University in Toulouse, France and collaborated with Dr. Yury Gogotsi and his research group at Drexel. The team published a paper on supercapacitors in Science magazine (J. Chmiola, G. Yushin, Y. Gogotsi, C. Portet, P. Simon, and P. L. Taberna, "Anomalous Increase in Carbon Capacitance at Pore Sizes Less Than 1 Nanometer," Science, v. 313, pp. 1760-1763, 2006), which helped Dr. Portet to secure this prestigious award.
