LaSIGE - Large-Scale Informatics Systems Laboratory is a research unit at the Department of Informatics, Faculty of Sciences, University of Lisboa.

LaSIGE performs a number of research activities in several sub‐areas of computer science and engineering including:

  • human-computer interaction and multimedia;
  • information management, net-centric, parallel and distributed computing;
  • software engineering;
  • security and dependability.

The current research lines pursued, which constitute guiding vectors for LaSIGE researchers, are:

  • Biomedical Informatics;
  • Fault and Intrusion Tolerance in Open Distributed Systems;
  • Human Computer Interaction and Multimedia;
  • Methods and Techniques for Engineering;
  • Software Systems;
  • Timeliness and Adaptation in Dependable Systems.

The laboratory human resources are organized in four research groups:

  • HCIM,
  • XLDB.

Research activities are normally organized around projects (national, international, in‐house), which facilitates progress and success control. Groups are fairly stable entities with formal leaders, and they champion or co‐champion research lines. Research lines are elastic with regard to human resources, in order to facilitate cross‐fertilization, and seek to be dynamic enough to adapt to the evolution of scientific and financing horizons, having an informal leadership and welcoming collaboration amongst members of different groups.

The duality group vs. research line allows separating concerns between the space and timeoriented views of LaSIGE. Groups are concerned with the space‐oriented view (structure and organization of the lab, logistics, interaction with the enveloping institution (FFCUL), etc.). The long‐term time‐oriented view is anchored on research lines, and this helps put in perspective the several projects (the short‐term time‐oriented view), in the most efficient and effective way.
