Maria Grammatikopoulou

About

Maria Grammatikopoulou is a pioneering researcher at the intersection of microrobotics, optical manipulation, and robotic-assisted surgery. Her work spans two transformative domains: the development of untethered microrobots for cellular manipulation and the enhancement of safety in minimally invasive surgery (MIS). In her highly cited 2017 work (52 citations), she introduced a laser-printing method using two-photon photopolymerization to create articulated microrobots that can be optically controlled for precise, non-contact cellular manipulation—overcoming the critical challenge of component stickiness. In surgical robotics, Grammatikopoulou has advanced the concept of Active Constraints (ACs) and motor channelling to prevent tool-shaft collisions and provide intuitive sensory feedback in master-slave systems, directly addressing the physical separation between surgeon and patient. Her recent 2023 work on spatio-temporal networks for video semantic segmentation in surgical videos demonstrates her continued innovation in computer vision for clinical applications. With over 100 total citations, Grammatikopoulou’s contributions are shaping the future of both micro-scale manipulation and safer, more effective robotic surgery.
