Biography

Kostas Alexis obtained his Ph.D. in the field of aerial robotics control and collaboration from the University of Patras, Greece in 2011. His Ph.D. research was supported by the Greek national-European Commission Excellence scholarship.

After successfully defending his Ph.D. thesis, he was a awarded a Swiss Government fellowship and moved to Switzerland and ETH Zurich. From 2011 to June 2015 he held the position of senior researcher at the Autonomous Systems Lab, ETH Zurich, leading the lab efforts in the fields of control and path planning for advanced navigational and operational autonomy.

His research interests lie in the fields of control, navigation, optimization and path-planning focusing on aerial robotic systems with multiple and hybrid configurations. He is the author or co-author of more than 50 scientific publications and has received several best paper awards and distinctions, including the IET Control Theory & Applications Premium Award 2014. Furthermore, together with his collaborators, they have achieved world records in the field of solar-powered flight endurance. Kostas Alexis has participated in and organized several large-scale multi-million dollar research projects with broad international involvement and collaboration. In July 2015, Kostas moved to the University of Nevada, Reno with the goal to dedicate his efforts towards establishing true autonomy for aerial and other kinds of robotics.
