AVISPA Research Group

AVISPA gathers together researchers from the Pontificia Universidad Javeriana at Cali and the Universidad del Valle, as well as from recognized european academic institutions such as the The French Acoustics/Music Research Institute (IRCAM) and the École Polytechnique of Paris.
AVISPA has been ranked as "A1", the highest quality qualification given to research groups by COLCIENCIAS (the Colombian Agency for Science and Technology Development).
Since 2008, AVISPA is an INRIA Associate Team with the FORCES project.

AVISPA aims at defining computational models that allow to understand the nature and the behavior of complex systems as the observation of the evolution and interaction of their processes. From a more practical standpoint, AVISPA seeks to verify the effectiveness of the proposed models by building applications intended to solve real problems in

• the sciences (e.g. modelling and verification of complex biological systems)
• the engineering (e.g. modelling and solving of scheduling/logistics problems, verification of communication protocols)
• the arts (e.g. formal languages and tools for computer music)

AVISPA focuses on the idea of interaction understood as the interchange/accumulation of information, as proposed by V. Saraswat in its concurrent constraint programming (ccp) model.

See AVISPA's profile on Colciencias Scienti.

See the AVISPA Poster (in Spanish) for a non-technical introduction to our research interests.

1. To devise models of concurrent processes that integrate different programming paradigms and that appropriately represent complex systems. Our interest is the (possibly automated) verification of fundamental properties of systems arising in areas such as distributed systems, systems biology, computer security and computer music.
2. To develop formalisms and tools for modelling and solving combinatorial problems, using techniques from (concurrent) constraint programming. Such tools could be useful in a wide variety of fields, including planning, resource assignment, musical composition, among many others.
3. To conceive and implement software tools for supporting multimedia interaction, mainly in the form of concurrent constraint-based tools and languages. We are particularly interested in developing software that supports the process of generating complex musical material while enacting rich forms of musical interactions.
4. To propose methodologies and tools for integrating formal models into the main stream of software construction
