Research interests

My research focuses on the development of teleoperation and supervision of real machines via the digital twin. It aims to optimize task execution by integrating simulated data from the digital twin with real machine data. This work contributes to the evolution of supervision and remote operation in Industry 5.0, by exploiting the advantages of immersive technologies. It promotes close collaboration between human and machine, with an enhanced interaction and safer operations.
