Keerthi Sagar

Hi there! I am a Marie-Curie Research Fellow at Irish Manufacturing Research CLG and KUKA, Ireland , where I am a part of the Robotics and Automation team. My involves robot motion planning, optimization, and control. I am currently working on optimization and control strategies to enable robots to perform fine and dexterous manipulation tasks using both autonomous and teleoperation techniques.

Before starting my Marie-Curie PostDoctoral Fellowship, I obtained my Ph.D. in robotics from University of Genova, Italy under the guidance of Prof. Matteo Zoppi and Prof. Dimiter Zlatanov .
