LASIGE - Large-Scale Informatics Systems Laboratory is a research unit of the Informatics Department (DI) of the University of Lisboa (UL), Faculty of Sciences (FCUL).

LASIGE has approximately 120 collaborators, amongst researchers with a doctoral degree, working toward a Ph.D., or Master students and other junior researchers. The current Director is Prof. Paulo Veríssimo.


Best Paper Award at ACM CHI 2014 Conference

LASIGE researcher Tiago Guerreiro was distinguished with a "Best Paper Award" at ACM CHI 2014, to happen in Toronto, Canada, April 2014, with the paper "B#: Chord-based Correction for Multitouch Braille Input". CHI, a Core A* conference, is the second largest ACM conference and the major conference on Human-Computer Interaction.

XLDB team with top results at OAEI 2013 and DREAM 8

The AML system developed by XLDB obtained top results in the Ontology Alignment Evaluation Initiative (OAEI 2013). XLDB also obtained high scores in all the evaluation criteria at the NIEHS-NCATS-UNC DREAM8 Toxicogenetics Challenge.

O Mundo em Pessoa - LaSIGE collaboration with Sapo Labs

O Mundo em Pessoa is a collaboration project that involved the research and development teams of LaSIGE and Sapo Labs and it's based on the automatic collection of quotes by Fernando Pessoa (orthonymous and heteronyms) from the social networks. The project is launched in 2013, when it's celebrated the 125th birth anniversary of the poet.

About LASIGE -- eXtreme Computing

LaSIGE develops activities in a number of relevant areas of computer science and engineering (CSE), including: human-computer interaction and multimedia; information management, net-centric, parallel and distributed computing; software engineering; and security and dependability.

The activities of LaSIGE represent an added value to the Portuguese and European S&TS (science and technology system) tissue, materialized by several factors:

  • Quality, quantity and impact of the outputs in research, technology transfer and advanced training.
  • Alignment with state-of-the-art international research themes and agendas (e.g. Horizon-2020), increasing impact and promoting prospective industrial exploitation.

LaSIGE’s scientific skills have been best evidenced in face of extremes:
extreme levels of threat; extremely low software defect requirements; extreme operating conditions; extreme uncertainty and dynamics; extremely large-scale data sets, flows and computations. These matters are addressed by all research groups without exception, representing a powerful differentiating factor of the lab:

“Extreme Computing - computer science and engineering pushed to the extremes of functional and non-functional properties of systems”.

LaSIGE follows a research-line centred strategy, whose objectives follow from the above, reconciling research freedom with a focus on extreme computing. Current research lines:


LASIGE research activities are funded by FCT (through the Multiannual Funding Programme and national research projects) and by international projects (mainly, projects financed by the European Commision).
