About

Dhan Thiruchelvam is a pioneering researcher in the field of magnetic actuation for robotic-assisted surgery, with a focus on minimally invasive abdominal procedures. His work centers on developing and refining local electromagnetic actuation (LEMA) systems that enable precise, dexterous surgical instrument control across physical barriers—a critical innovation for reducing surgical trauma. Thiruchelvam’s most cited paper, a 2016 review on magnetic surgical instruments (53 citations), established foundational insights into magnetic-based approaches for abdominal surgery. He further advanced the field by modeling and controlling local magnetic actuation (LMA) systems, addressing key challenges such as magnetic interference between neighboring actuator sets and disturbance rejection in multi-degree-of-freedom configurations. His contributions have been recognized through publications in high-impact robotics and surgical journals, with cumulative citations exceeding 80. By tackling the complex magnetic interactions that arise when multiple actuation units operate in close proximity, Thiruchelvam has paved the way for more reliable and effective robotic platforms for abdominal surgery, offering a compelling alternative to traditional mechanical linkages.
