research snapshots

We conduct systematic research on mass customization, short-run and high-value manufacturing, and controls of complex systems.

Additive manufacturing

Control in different time scales: from precision laser-material interaction for aerospace and medical application to process reconfiguration and reclaiming materials.

robotics and learning FROM limited feedback

Robot control and collaborative sensing for systematic fast control under slow e.g. vision feedback.

Adaptive control

We were among the 3 teams that achieved the top results in an international benchmark on adaptive regulation.
