Assistant Professor in Robotics
Electrical & Computer Engineering Dept., University of Patras, Greece

I build robots that learn, adapt and act safely in the real world — combining reinforcement learning, evolutionary optimization and optimal control, and testing the results on physical hardware.

I lead the robot-learning work of the Laboratory of Automation & Robotics (LAR) at the University of Patras. My group designs algorithms — from Quality-Diversity search to structure-exploiting trajectory optimization — and evaluates them on physical robots, from legged platforms to manipulators.

Previously, I was a post-doctoral fellow at LASA, EPFL and at the Computational Intelligence Laboratory, University of Patras, where I was Principal Investigator of the H.F.R.I.-funded NOSALRO project (2022–2025). I hold a PhD in Robotics and Machine Learning from the University of Lorraine / Inria Nancy (LARSEN team).

Robot learning, evolutionary optimization and optimal control — algorithms that work on physical robots, not only in simulation.
