Georgia Chalvatzaki is an Full Professor at TU Darmstadt since April 2023. Before that, she was an Independednt Research Group Leader from March 2021, after getting the renowned Emmy Noether Programme (ENP) fund of the German Research Foundation (DFG). This project was awarded within the ENP Artificial Intelligence call of the DFG – only 9 proposals out of 91 proposals were selected for funding. It enables outstanding young scientists to qualify for a university professorship by independently leading a junior research group over six years.
In her research group iROSA, Dr. Chalvatzaki and her new team will research the topic of "Robot Learning of Mobile Manipulation for Assistive Robotics". Dr. Chalvatzaki proposes new methods at the intersection of machine learning and classical robotics, taking one step further the research for embodied AI robotic assistants. The research in iROSA proposes novel methods for combined planning and learning for enabling mobile manipulator robots to solve complex tasks in house-like environments, with the human-in-the-loop of the interaction process.
From October 2019, she was a Postodoctoral researcher at the Intelligent Autonous Systems group, advised by Jan Peters. Dr. Chalvatzaki completed her Ph.D. studies in 2019 at the Intelligent Robotics and Automation Lab (https://robotics.ntua.gr/ ) at the Electrical and Computer Engineering School of the National Technical University of Athens, Greece, with her thesis "Human-Centered Modeling for Assistive Robotics: Stochastic Estimation and Robot Learning in Decision Making." During her career, she has worked on eight research projects, and she has published more than 30 papers ((https://scholar.google.com/citations?user=mlho5FkAAAAJ&hl=en ) ), most of which in top-tier robotics and machine learning venues, e.g., ICRA, IROS, RA-L.
