About me

I am a Senior Researcher at Tampere University and Academy of Finland Research Fellow. I lead a research group Light Robots. Click here to see more about Light Robots ambition

We work at the interface between physics, soft mechanics and material engineering. We are interested in developing general research routes for materials robotics that are out of equilibrium, locomotive, interactive, and capable of self-feedback, adaptation, and communication.

Research topics

We seek ideas for imaginative projects.

FAIRY will take a significant leap in material science to develop small-scale light driven flying robots with adaptive features inspired by biological organisms.

OPTOPUS aims at developing a new type of wireless soft robotic system with overall size in a millimetre range, that is capable of sophisticated functions when fuelled by light energy only.

OSCILLATE aims to develop new concepts of self-oscillators that can perform non-reciprocal, multi-mode and zero-energy mode movements upon light excitation. Bioinspiration is our general guideline, and we wish to create new concepts of optical feedback mechanisms for robotic interaction, which can be generalized to other materials or chemical systems.
