Context of the project

My current research activities take place in the MGS project. This project evolves following two complementary directions:

  1. to study and develop the integration of topological notions and tools in programming languages;
  2. to apply those notions and tools to the conception and development of new data- and control-structures that are expressive and efficient for the modeling and simulation of dynamical systems with a dynamic structure.

This research is concretized by the development of an eponymous experimental programming language and its application to the modeling and simulation of dynamical systems. We have a particular focus in the field of biology and morphogenesis.

Internships

We have proposed some internships on these topics in 2004, 2005, and 2008. Feel free to contact me if you would like to work on this topic. Whatever your background is (physics, biology, mathematics, computer science, etc.) we can always manage to find you a suitable subject.

High-level Domain Specific Programming Languages

My research work in that domain focuses on the definition of new data- and control- structures allowing the representation of spatial and temporal data for the modeling and simulation of dynamical systems in a rigorous framework, close to the end-user and the mathematical tools used in that domain (dynamical systems in biology, chemistry and physics).

The two main applications domains that have motivated the development of these new mechanisms are the analysis and representation of complex relations (for example spatial ones) and the simulation of dynamical systems where the structure has to be computed jointly with the evolution of the system (as it is the case in developmental biology, at any level from the cells to the individuals).

A privileged application domain was the modeling and simulation in systemic biology (more specifically in post-genomic and in integrative simulation of developmental processes). We are now (since 2007) considering the modeling, simulation and conception of new computational resources brought by nanosciences and molecular biology.

This research is based on the development of a new computation paradigm (by generalizing the approaches of the chemical computing, membrane computing, Lindenmayer systems and cellular automatons) and new tools for the interpretation, typing and efficient compilation of declarative languages. This research meets the fields of the “self-*” (self-sustaining, self-healing, self-organizing) systems that are emerging in the software community and whose long-term goal is to identify and develop in today’s computers the fundamental requirements to ensure properties of flexibility, adaptivity, robustness, self-healing that are common to the complex systems of living matter.

The MGS Project

Everything that concerns MGS and spatial computing can be found in its own webpage. Many examples are given in the image gallery and the interpreter can be found here.

MGS has been used as a modelling language for the Paris team of the MIT iGEM's 2007 competition. The source code of the models can be run with the current version of the MGS interpreter.

The french project is targeted to the construction of a multicellular bacterial organism made of two co-existing cell types. Brainstorming resulted in proposing a system made of so-called soma cells, that produce a metabolite (DAP), and will not be able to divide, and of so-called germ cells that are able to grow, but only in presence of (sufficient quantities of) DAP, and are able to differentiate into soma cells. Informal reasoning indicate that this design should be correct, in the sense that it leads to an exponential growth of the two coexisting cell types. However, before actually constructing this system, the design has been assessed using several models at different levels mainly implemented in MGS.

The Amalgams

Taking part in the 8 1/2 project, I have defined a formalism based on names an name capture.

Binding and substitution of bound variables are major is- sues in the design of languages. The mechanism of name capture lies at the heart of modular, incremental and object-oriented programming. In this formalism, we address the problem of names and name capture on its own by designing, through the use of three operators, a complete and consistent mechanism of name capture for a declarative framework. We perceive expressions with free names as incomplete expressions which will be dynamically completed by a name capture mechanism. The formalism allows the definition of first-class environments. We apply this mechanism to model distributed incremental program construction and to define an object oriented programming style in a declarative language.

Very little is available on the amalgams in english. A good introduction, while never published, is here.

More can be found here.
