About

Alexandra Karavasili is a researcher specializing in assistive and rehabilitation robotics, human-robot interaction (HRI), and the development of psychometric tools for evaluating assistive technologies. Her work sits at the intersection of robotics engineering and user-centered design, with a particular focus on improving mobility and cognitive support for elderly individuals and people with movement impairments. Karavasili has made significant contributions through her involvement in two major robotic rollator platforms — MOBOT and i-Walk — developing and refining the communication models, HRI frameworks, and evaluation strategies that underpin these intelligent assistive devices. Her iterative, user-centered design methodology, demonstrated across multiple studies totaling over 110 citations, reflects a deep commitment to ensuring that robotic assistants are both technically robust and genuinely responsive to end-user needs. Perhaps her most distinctive contribution is the development of PYTHEIA, a validated psychometric scale designed to assess user satisfaction with assistive and rehabilitation technologies — addressing a critical gap in the field where no standardized measurement instrument previously existed. This tool has since become a valuable resource for researchers evaluating assistive devices more broadly. Through her sustained, multidisciplinary research, Karavasili has established herself as an influential voice in making assistive robotics more accessible, effective, and human-centered.
