Welcome to my research webpage !
Our research group is affiliated with the Department of Electronics, Optronics and Signal Processing (DEOS) at the ISAE-SUPAERO. Our research is mainly focused on novel microwave circuits and antennas exploiting plasma discharges.
We are currently looking for brilliant and highly motivated graduate students and postdocs to join our group. So, do not hesitate !
