My major research areas of interest are as follows:
Architectures and Technologies for the Future Internet
Since leaving BT Research in 2009, I have been focusing on Internet architecture related issues during my work at Cambridge University. The activities are a mix of technical but also community-related work.
- Large-scale Publish Subscribe
- The EIFFEL Initiative
- Mobile-Centric Wireless Sensing
- Socio-economic Evaluation of Large-Scale Systems
Seamless and Context-aware Services
After joining Nokia Research in 2000, I started my work in the area of seamless and context-aware services. This topic comprises aspects to provide protocol and service functionality in a multi-dimensional heterogeneity, i.e., in the presence of heterogeneous access networks across operators and device boundaries. It further considers the adaptation of service and application functionality based on the currentcontext of the user. Context includes, but is not limited to, information about location, presence, current activity, affective state, or other information of the user.
