Hi! I’m Sayantan, a postdoctoral researcher at the Learning and Intelligent Systems (LIS) Lab led by Prof. Dr. Marc Toussaint at Technische Universität Berlin, Germany. My current research focuses on reinforcement learning and sim-to-real transfer in robotics, including developing mechanisms for effective zero-shot transfer and fast, data-efficient adaptation on real systems to handle changes after deployment.

I earned my PhD from Universität Innsbruck, Austria, under the supervision of Prof. Dr. 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 Prof. Dr. Stefan Wermter.

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