Position

I am Nikolas' and Yiannis' father. I am also a professor in the Department of Computing Science and Engineering at Chalmers University. I am the co-leader of the Distributed Computing and Systems Research Group. Formerly I was with these institutes.

My CV in pdf can be found here.

Research Interests

My current research interests center on distributed/parallel computing and systems and information visualization in general. More specifically my research interests include:
- efficient and fault tolerant inter-process communication/coordination mechanisms, with applications in: i) Lock-free programming and lock-free data structures for multicore and many core systems, in particular on the PEPPHER project, the NOBLE library project and the Euro-TM project. The WARPing, the Lockless-Spark98&Lockless-miniSPLASH2, the NBmalloc, the  Dynamic Load Balancing on Graphics Processors projects were also projects from the same general area. ii) Algorithms for multicore systems, in particular in the GPU Quicksort project.

- Secure Network Services and Communication.

- communication and data fusion in mobile systems in particular on the MiNEMA programme and the DYNAMO action;
- visualization of distributed algorithms, files, networks and software, in particular on the LYDIAN, the CausalViz, the CiteWiz and the TrustNeighborhoods projects.
- interactive visualization for reducing occlusion in 3D environments, in particular on the PMorph and the "Image-Space Dynamic Transparency" projects. 

For more information please have a look at the page of the distributed computing and systems research group, you can also look at the list of my publications. A couple of news and press releases from Chalmers (in Swedish) regarding our research can be found here and here.
