The collaborative research grant between the inverse scattering group of Profs. Cakoni, Colton and Monk and DeFI Group at the Centre de Mathématiques Appliquées at Ecole Polytechnique, Paris has been renewed for three more years, 2011-2013. This collaborative program has been successfully running since 2008 and was highly regarded by the midterm evaluation panel. The panel recognized the research teams at Delaware and Ecole Polytechnique as among the leading researchers in the world in the emerging field of qualitative methods in electromagnetic inverse scattering theory. The funding is provided by the French “Institut National de Recherche de Informatique en Automatique” (INRIA) and is available for the exchange of graduate students, postdoctoral students and faculty members during this period. The research team at Delaware is headed by Professor Fioralba Cakoni and at the École Polytechnique by Dr. Houssem Haddar.
