Hi! I’m Sayantan, a postdoctoral researcher at the Learning and Intelligent Systems (LIS) Lab led by Marc Toussaint at Technische Universität Berlin, Germany. My current research focuses on reinforcement learning and imitation learning in robotics. More specifically, I work on developing mechanisms for effective, resource-efficient, and long-term adaptation to out-of-distribution scenarios for robots.

I earned my PhD from Universität Innsbruck, Austria, under the supervision of Justus Piater, where I worked on continual learning for manipulation, learning from demonstration, and sim-to-real transfer. Previously, I completed my MSc (with distinction) at Universität Hamburg, Germany, working closely with Stefan Wermter.

If our interests align, feel free to reach out — I’d love to connect!
