May 6, 2026ย โ The research group of Prof. Hongliang Ren was pleased to host Prof. Pierre Dupont as part of the Faculty of Engineering Distinguished Lecture series.
Prof. Dupont is a Professor of Surgery at Harvard Medical School, Chief of Pediatric Cardiac Bioengineering at Boston Childrenโs Hospital, and an IEEE Fellow. In his talk titled โContinuum Robotics for Minimally Invasive Interventions: Design Tradeoffs for Clinical Applications,โ he presented an engineering perspective grounded in realโworld clinical challenges.
Prof. Dupont discussed three complementary continuum robot architectures โ concentric tube robots, magnetic ball chains, and tendonโactuated systems โ each involving distinct tradeoffs in stiffness, steerability, force capability, and hysteresis.
Key highlights from the lecture:
- Concentric tube robots enable precise intracardiac catheterization and bimanual neuroendoscopy.
- Magnetic ball chains offer outstanding steerability for cardiac ablation procedures.
- Tendonโactuated systems provide a balanced tradeoff between stiffness and dexterity for transcatheter heart valve repair.
The lecture illustrated how tailoring robotic designs to specific clinical constraints can meaningfully expand the capabilities of minimally invasive interventions.
Short bio of Prof. Pierre Dupont
Prof. Dupont received his B.S., M.S., and Ph.D. in Mechanical Engineering from Rensselaer Polytechnic Institute. He was a Postdoctoral Fellow at Harvard University, later a Professor of Mechanical and Biomedical Engineering at Boston University, and is now Chief of Pediatric Cardiac Bioengineering at Boston Childrenโs Hospital and Professor of Surgery at Harvard Medical School. He is an IEEE Fellow, a former Senior Editor for IEEE Transactions on Robotics, and a member of the Advisory Board for Science Robotics.
Audience engagement
The lecture attracted faculty members and students from engineering and medical backgrounds, followed by a lively Q&A session. Attendees appreciated Prof. Dupontโs clinically driven approach to robotic design, and the discussion continued informally after the talk.
