Stefania Ketzetzi is an experimental physicist who carries out research in the area of soft condensed matter.
She earned her BSc degree from the Aristotle University of Thessaloniki (2014), MSc degree from the University of Amsterdam (2016, thesis advisor Daniel Bonn), and PhD from the Leiden Institute of Physics LION (2021, thesis advisor Daniela Kraft).
She is currently investigating active colloidal particles with adaptive motility through surface interactions as a Postdoctoral researcher at ETH Zurich (advisor Lucio Isa). Here, her aim is to realize bioinspired active particle navigation systems based on direct environmental sensing and response. The ultimate goal is to propose novel design rules for creating active materials with true functionality, eg, efficient navigation and task performance, that may aid the implementation of artificial active agents in future applications inside complex environments.
She is also a teaching assistant for graduate-level courses in materials science, and a member of WiNS (Women in Natural Sciences) where she is actively involved in launching a student mentoring program.
