Georgia Chalvatzaki received her Diploma degree in Electrical and Computer Engineering from NTUA in June 2012. Since October 2012, she is a PhD Candidate, under the supervision of Asst. Prof. Costas Tzafestas at the School of Electrical and Computer Engineering of NTUA, and serves as a research assistant within the Intelligent Robotics and Automation Lab (IRAL) of ICCS. Her research interests and expertise include human detection and tracking with applications in the field of assistive robotics. She has especially worked in the development of algorithms for robust on-line human gait tracking and non-intrusive assessment from laser rangefinder data using stochastic estimation techniques for the control of an intelligent robotic walker device for the elderly, in the frames of the MOBOT EU research project. She is currently working as a research assistant in the BabyRobot (H2020) project. She is a member of the Technical Chamber of Greece since 2013. She is, also, a member of IEEE, IEEE Robotics & Automation Society, IEEE Young Professionals, IEEE Women in Engineering, IEEE Robotics and Automation Society, IEEE Systems, Man, and Cybernetics Society.
