About
Sagar Chowdhury is a pioneering robotics researcher whose work spans microrobotics, optical manipulation, and biomedical applications of small-scale robotic systems. With a career built at the intersection of robotics, biology, and medicine, Chowdhury has made foundational contributions to two major areas: the autonomous control of magnetic microrobots and the optical manipulation of biological cells. His most influential work, "Controlling Multiple Microrobots" (2015, 106 citations), established critical frameworks for coordinating swarms of microscale robots — a persistent challenge in the field. Complementing this, his series of papers on independent magnetic microrobot navigation introduced novel path-planning algorithms enabling collision-free autonomous movement, advancing the practical viability of microrobotic systems. On the optical side, his surveys and experimental studies on optical tweezers (73 citations) helped systematize indirect manipulation techniques for cells and biomolecules, while his holographic triplet-trap gripper demonstrated elegant, noninvasive cell handling. More recently, Chowdhury has pushed toward real-world biomedical impact, developing soft magnetic millirobots for targeted drug delivery in the central nervous system and demonstrating tetherless surgical suturing — work that positions microrobotics as a transformative force in minimally invasive medicine.
