We are the Navigators, a research team on distributed systems, their architectures, their algorithms, in their several skins: fault tolerance, real-time, security, and combinations thereof.
We also pursue the quest for the right balance between science and technology. Some people say that Informatics (a.k.a. computer science and engineering) belongs to a new breed, of what are called techno-sciences. We believe that techno-scientists should accompany theoretical mastery with a deep knowledge of their environment — computer technology — as well as astro-physicists know the sky, or marine biologists know the sea.
We study new theories to explain distributed systems, and new algorithms to take advantage from them. But we also like to do proof-of-concept experiments about the theory we work on. We try that our papers and theses tell a good story as clearly as possible. We work hard for our demonstrations to be convincing and captivating. Because we believe science is made for others.
- (1/Sep/2016) A H2020 research project lead by the Navigators group has started. The project is called: DiSIEM - Diversity enhancements for SIEMs
- (1/July/2016) We have initiated a new FCT research project. The project is called: IRCoC - Intelligent Resilience for Cloud-of-Clouds Services
- (1/Jan/2016) We have started a collaboration project with colleagues from Brasil, which is supported by CAPES-FCT. The project is called: Resilient Supervision and Control in Smart Grids
