Hélène Roussel earned her PhD from Université Pierre et Marie Curie (UPMC-Paris 6), France, in 1993. She has been a professor at Sorbonne University since 2009 and conducts her research within the GeePs Laboratory, a joint unit of CNRS, Sorbonne University, CentraleSupélec, and Université Paris-Saclay in Paris, France. She currently serves as Deputy Director of the Engineering Department at Sorbonne University. Her research focuses on numerical methods and fast algorithms for electromagnetic scattering and radiation in complex media. Applications of her work include the study of metamaterial-based antennas, the analysis of wave propagation and scattering in complex media for target detection, medical imaging using microwave cameras, and remote sensing applied to the study of natural environments.
