Welcome to Blai Vidiella personal website
I am a researcher at Nonlinear dynamics and evolution Lab (NoDE) of the Centre de Recerca Matemàtica (CRM). This year (2022), I have acomplished my PhD thesis entitled "Terraforming Earth's ecosystems : engineering ecosystems to avoid anthropogenic tipping points" at Complex Systems Lab (CSL) of the Universitat Pompeu Fabra (UPF) in Barcelona, supervised by Ricard Solé , Josep Sardanyés and Núria Conde. I am designing, modelling, and sometimes testing, engineered systems for holding ecosystems before a tipping point. For this reason, I apply concepts from different areas such as: ecology (in order to know what is needed), computation science (abstract design of the needed circuits), synthetic biology (for the organism engineering), dynamical systems (for instance ghost phenomena and chaos) and mathematical modelling (to test and predicting behaviour). After my thesis, we understand better some endangered ecosystems and we have more insights of how sustaining them using biological agents. Will we be able to Terraform our planet?
My background is a Bachelor in Biomedical Engineering and a Master of Sciences in Mathematical Modeler of Complex Systems. I have been interested in Complexity and Dynamical Systems since my first lessons in the Biomedical Engineering degree. The question of how these two branches of science can give simple explanations of the emerging properties of natural systems is fascinating.
My interests make me collaborate during my Degree and Master studies with the Complex Systems Lab (CSL) and Dynamical Systems Biology Lab (DSB) from the UPF. In the DSB lab I have been supervised by Jordi Garcia Ojalvo, and we have studied the expression patterning in the gastruloids, the effects of noise in the cell division and the echo phenomena in synthetic biological oscillators. In the CSL I had been researching about how engineering synthetic bacteria to behave as an immune system, and engineering the semi-arid ecosystems to improve them in front of the global Climate Change conditions, and the study of the plastic ocean ecosystem crated by the human society.
Nowadays, my research is focused in the Terraformation of ecosystems. In order to achieve the possibility to engineer the ecosystem, we must learn several topics to predict the viability of our Terraformation strategy. Some of the topics needed are: Population dynamics, Synthetic Biology, Systems Biology, Dynamical systems, Biological Computation and Spatial Analysis. Complexity science provide us the landmark to understand the whole phenomena, even when their parts can not explain the behaviour of the system by themselves.

- Human induced environmental perturbations are forcing ecosystems to change to survive. Our approach to this problem using Synthetic Biology. Engineered organims to increase ecosystems resiece. ◈ ◈ ◈
- The organisms are not isolated from their environment. They live in communities. The processes of cooperation, predation, mutualism or exclusion are important to understand how the population evolve. ◈ ◈ ◈ ◈
- Under the threats of Climate Change, understanding the natural dynamics behind the bio-geo-chemical cycles is crucial. Nowadays, species may be changing the way in wich they interact (for instance, from mutualism to predation, competition or parasitism). ◈ ◈ ◈ ◈
- Being able to build systems that are alive and perform a desired function is fascinating. The living systems have abilities that make them better than machines to be used in some engineering scales and from some desired proposes. ◈ ◈ ◈ ◈
- The integrative view is the approach that Complex scientist must agree. In the case of biology, the individual molecules can not explain interesting phenomena such as Life or Conscience.
- Any system can be descrived as interactions between individuals (from molecules to planets or trphic chains). How are they aranged? How they evolve? ◈ ◈
- Understand and build the mechanism that make organisms are able to sense and react in front of the environmental changes. The computation of the external signals, integration and reaction is what makes a difference in the biology. ◈ ◈
- In Complex Systems it is frequent to find fractal structures. This means that the generating function is the repetition of the building blocks in all the different scales. This is usual to find also in biology because this optimize the information needed to build the structure (trees, blood circulation and even the brain).
- Understanding that a system that we can describe their rules and even make calculations of it, It's unpredictable and it will not be predictable! ◈ ◈
- Evolution have changed the way we see Nature. Nowadays, we can use it to improve engineers designs, mimic Nature in silico or even understand and predict the development of human societies.
