Welcome to DEXL Lab

Data Science - Artificial Intelligence - Big Data

The Data Extreme Lab  is a research group of the National Laboratory of Scientific Computing (LNCC) involved in research, development and graduate studies in Data Science, Artificial Intelligence and Big Data.Our work is founded in Computer Science principles,  techniques and methods to be applied to problems raised in different disciplines, such as: Astronomy, Biodiversity, Oil and Gas, Sport Science, Smart Cities etc.

The DEXL group was granted the coordination of the National Institute of Science and Technology (INCT) in Data Science, a national initiative to orchestrate the development of Data Science in Brazil involving Universities and Research Institutes. In 2018, the DEXL Lab organized the 34th International Conference in Very Large Data Bases, held in Rio de Janeiro, and attracting more than 800 top researchers form all around the world.
