I am a Post Doc in the Humanoids and Human Centered Mechatronics (HHCM) research line at the Istituto Italiano di Tecnologia (IIT) in Genoa, Italy. My research focuses on mechatronic systems for legged and wearable robotics, with the aim of developing energy-efficient and trustworthy robots and sensing systems.
