Objectives
Understanding the properties of 'complex systems' with a large number of highly interconnected heterogeneous
elements poses today a grand challenge for system research.
Examples of such systems include the Internet, critical infrastructures -like computer networks or power grids - and
signalling and regulatory networks in biology.
For such systems we can design components and their connections but the problem remains of how to guide them to
achieve desired global behaviours, like dependability and adaptability, and how to predict and avoid undesired
behaviours, like cascading failures in interconnected infrastructures.
In the life sciences, novel data acquisition techniques provide a wealth of data on living systems but we lack
sufficient means to infer models from these data.
The objective is therefore to develop scalable computational modelling and inference tools and scalable simulation
techniques for complex systems and in particular to:
- Infer system models - the dynamic laws governing the components and their interactions - from high volume,
possible incomplete or uncertain data.
- Develop models of emergence of aggregate behaviour that will permit the formulation of design strategies
for systems with a specified aggregate behaviour
Focus/Approach
One or more of the following research issues should be addressed:
- Multi-scale simulations: Develop methods for the effective computation of systems acting/described on different
levels of aggregation.
- Simulation in presence of uncertainty: Develop computational tools that take into account the fact that the
models themselves as well as the parameters that they use may be uncertain.
- Reconstruction of system models from incomplete, missing or inconsistent sets of data.
- Integrated modelling and simulation environments: Matching large amounts of data against models
UM/EEng Competences
Competences:
- Machine Learning / Data Mining
- Bioinformatics
- Modeling and optimization of bioprocesses
- Artificial Neural Networks;
- Evolutionary Computation;
- Networking / Internet
The study of complex systems has not been an area of active research at Univ. Minho
but there are basic competences that allow this to be an area to focus in the future.
There is a clear need to find partners with competences in the life sciences
fields (Biology, Biotechnology, Health care, etc) which are available in our
School of Engineering.
