Research in Complex Systems  
In the vast land of complex systems, I commute back and forth between computational biology and bio-inspired computing. On the way, I founded the field of morphogenetic engineering (ME), which explores new methodologies to model and create complex architectures that self-organize from a swarm of heterogeneous agents, in particular by development. Such emergent structures can be modular robots, synthetic organisms, or large autonomic networks of computing devices. ME could also explain brain representations based on dynamic "neural shapes" in phase space, formed by myriads of correlated spikes. Additionally, I am interested in the evolutionary mechanisms leading to diversity, and how they can help us understand and automate the design of ME systems.
Complex systems are characterized by the self-organization of small, repeated elements into large-scale patterns. They are abundant in our environment, whether as natural structures (physical, chemical, biological) or spontaneously emerging human organizations (cities, markets, Internet). Such decentralized, self-organized and unplanned systems are probably the most common and efficient type of systems. It is centrally designed systems that are unique and costly to build, as they require another intelligent system (human or human-made machine, in a recursive fashion) to exist and operate. In fact, "complex" systems might well turn out to be the simplest.

In this context, natural systems can play an important role in providing a powerful source of inspiration toward new technologies. Understanding natural self-organization could help create a new generation of artificial systems with properties still largely absent from traditional engineering, such as decentralization, autonomy and adaptivity. Toward this goal, my research is positioned at the interface between the science and the engineering of complex systems, focusing on biological topics and bio-inspired principles. It tries to cover both the computational modeling and simulation of biological self-organization (such as development, neural networks, or population dynamics) and the engineering of "intelligent" devices inspired by these phenomena (such as swarm/modular robotics, distributed computing, or language processing):

  • Theoretical & Computational Biology: The pervasiveness of complex systems is most striking in biology, at all scales of resolution from molecules and cells to organisms and populations. Agent-based, computational modeling and simulation is a powerful tool to explore biological complex systems, including gene regulation, morphogenesis, neural networks, and evolution.

  • Bio-Inspired Computing & Bioengineering: In parallel to biological modeling, another important goal is to explore artificial systems consisting of a multitude of micro-programmed elements interacting locally. The motivation is to obtain new architectures and powerful functionalities from "bottom-up" self-organization, ones that cannot be directly designed "top-down" by engineers. ← Less
