Chao Liu

Chao Liu is a Research Scientist at CNRS (French National Center for Scientific Research) since 2008, affiliated with the DEXTER team and the Department of Robotics, LIRMM at University of Montpellier, France. He earned his Ph.D. in Electrical & Electronic Engineering from Nanyang Technological University, Singapore (2006).

• Current research focuses on surgical robotics, haptics, teleoperation, and nonlinear control theory with applications in computer vision.

His work addresses challenges in robotic-assisted telesurgery, including:

• Stable and transparent human-robot interaction through wave variable compensators and passivity filters
• Physiological motion compensation using spatio-temporal LSTM and dual Kalman filters
• EMG-based motion recognition for surgical skill assessment
• 3D soft-tissue reconstruction with stereo-endoscopes and deep learning

Dr. Liu leads European and French projects like:

• TS2RT (CNRS-funded): Safer teleoperation with motion compensation
• ROBACUS (ANR-funded): Needle positioning with MPC control
• HaTUMoCo (CNRS-funded): Haptic teleoperation with uncertainty handling
• ARAKNES (EU-funded): Microrobotic systems for endoluminal surgery

Scientific honors include Senior Member of IEEE and Member of Sigma Xi. He supervises Ph.D. and Master's students working on topics such as concentric tube robot optimization, haptic teleoperation, and EMG-based force estimation. Dr. Liu serves on IEEE Technical Committees for Telerobotics and Haptics, and as Technical Editor of IEEE/ASME Transactions on Mechatronics.
