Research Laboratories

Advanced Information Management

http://aim.cs.uct.ac.za

The AIM Laboratory is loosely formed around the ideas of creating and managing information. The AIM group consists of Prof. Berman, Dr Kuttel, Prof. MacGregor, Prof. Marsden, Dr Potgieter and Dr Suleman. The research areas covered include databases, conceptual modelling, persistent programming languages, object-oriented databases, scientific computing, parallel and distributed computing, client/server computing, object technology, digital libraries, complex adaptive systems, distributed artificial intelligence, component-based software engineering and information retrieval.

Collaborative Visual Computing

http://www.cs.uct.ac.za/Research/CVC/

The Collaborative Visual Computing (CVC) laboratory consists of four full time academic staff members (Prof. E. H. Blake, A/Prof. G. Marsden, Dr J. Gain and Dr P. Marais) and numerous research students. The group forms an integral part of the Telkom and Siemens Centre of Excellence in ATM and Broadband Networks and their Applications, a joint undertaking by the University of Cape Town, the University of the Western Cape and the University of Stellenbosch. The CVC lab brings together expertise in graphics, interface design and psychology. Typical areas of research include: virtual modelling, visualisation, mobile computer interfaces, scene rendering and collaboration in virtual environments. The lab is involved in work funded by a number of South African agencies, including the NRF, THRIP and the Innovation Fund (initiated by DACST). Industry sponsors of our research include Telkom, Siemens and Microsoft.

Data Network Architectures

http://www.cs.uct.ac.za/Research/DNA/

The DNA Group consists of Professor Pieter Kritzinger, Adjunct Professor Andrew Hutchison, a previous graduate of the group and now working for T-systems (Pty) Ltd and Justin Kelleher, as team members. The DNA Laboratory specialises in the security, correctness analysis, performance analysis, design, specification and modelling of stochastic concurrent communicating systems (SCCS) in general, and telecommunication systems in particular.
