Research activities

Over the last 10 years or so, I have been working on the following projects

which are detailed below (more can be found in Research).

The MGS Project (2000-)

This work is in collaboration with J.-L. Giavitto, A. Spicher and J. Cohen.

New sophisticated applications are simulations of dynamical systems with a dynamical structure. Paradigmatic examples, in the context of Evry are given by developmental processes in biology. The modelling and the simulation of these processes are one of the goals of the systemic biology program. They have motivated the start of the MGS 1) project soon after the involvement of the LaMI into bio-informatics.

MGS is a rule-based language. A rule is similar to a rewriting rule but acts on almost any kind of data structure. This is possible through a unifying point of view where each data structure is equipped with its neighborhood relationship. The neighborhood relationship enables the definition of a suitable notion of part and a rule specifies the replacement of a part by another part. A set of rules is called a transformation. The definition of a transformation is similar to the specification of a function by case and transformations can be smoothly integrated into any functional language like ML.

More on this project can be found in the MGS web page and in Research.

The 8 1/2 Project (1992-2000)

This work was in collaboration with J.-L. Giavitto and J.-P. Sansonnet.

The 8 1/2 project has grown in the 1990’s in a computer architecture team developing new parallel architectures. As a matter of fact, stream representing trajectories are also sequential threads of control and multiple streams mean parallel threads of computation. In addition, the instantaneous state of a dynamical system is often a massive object (e.g., in finite elements methods) that can be computed using data-parallel operations. My contributions in this project rise at a moment where the static core (i.e., the features of the language that can be statically analyzed with respect to the parallel implementation) was well understood and where new dynamic data and control structures had to be designed and developed to face more sophisticated applications.

More on this project can be found here and in Research.

Teaching activities

At the university of Paris Est

I give this year two courses at the École Supérieure d'Informatique Appliquée à la Gestion

one course, with F. Gava and A. Spicher, at the Computer System's Safety Master at Université Paris Est

and one (very short) course, with J.-L. Giavitto, at the Interdisciplinary Approcah to Life Science Master

More is found here.

Previously at the university of Evry

I then taught2) at the university of Evry from 1997 to 2007 in the following courses:

I have a lot of slides for most of these courses; they are available upon request.

At the university of Orsay

I started my teaching activities as I was a Ph.D. student at Orsay. I taught three years of Logo as a mean to bring students to the notions of data and control structures. It is an interesting easy to learn (unlike Forth) functional language that has very simple graphic commands that, once combined, produce complex drawings. It is a good way of explaining –and convincing of the importance of– recursive programming.

2) in Europe, we now have the LMD system which has three basic years (L1, L2, and L3) corresponding roughly to undergraduate, two advanced years (M1, and M2) corresponding to the Master's degree and three thesis years corresponding to the Ph.D. For those reading french, the government has a web page that explains all the details.
