Overview and Interests

My research aim is to create a world where everything - people, devices, programs - is always connected in a personalised way through any medium. It is based on the discovery of new uses and supporting technologies for computers and communication systems.

Furthermore, I want to extend the computer and information systems to observe the real world and automatically modify the systems' behaviour to suit the prevailing conditions. Such "sentient" computing systems will play a key part in ensuring the sustainability of our planet.
