Professor Brad Nelson at the Institue of Robotics and Intelligent Systems operates an Octomag - an instrument whose eight electromagnetic coils permit maneuvering micro-robots through the eye to deliver drugs to the retina.

Roman Kappeler

Roman Kappeler is in the doctorate program of the Electronics Laboratory, ETH Zurich

In 2006 Roman Kappeler joined the Communication Photonics Group and is now working on a project aiming towards the implementation of a photonic crystal based SOA (Semiconductor Optical Amplifier). His focus is on the modeling of active photonic crystals.
