From Navigators
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.
Our greatest riches are our culture, and our researchers and students. If you believe in the former, you can become one of the latter. Welcome!
Announcements
- (1/Oct/2018) The (FCT-funded) research project AQUAMON -- Dependable Monitoring with Wireless Sensor Networks in Water Environments -- started today. During the next 3 years we will develop a dependable monitoring platform for application in aquatic environments using wireless sensor networks.
- (1/Oct/2018) The (FCT-funded) research project uPVN -- User-centric Programmable Virtual Networks -- started today. During the next 3 years we aim to build the next generation of virtual networks: VNets that are fully programmable.
- (20/Sept/2018) The NavTalks seminars have started for a new year of research presentations and useful discussions.
- (1/Aug/2018) The (FCT-funded) research project SEAL-- SEcurity progrAmming of web appLications -- started today. During the next 3 years we will design and build tools to make your web applications more secure!
- (11/Apr/2018) Based on the final demonstration of the Supercloud project last month, here is a video about Sirius, the multi-cloud network virtualization platform.
