Master in Science of Complex Systems

To candidate to the program, please follow the instructions underneath.

The “Complex Systems” master training, with emphasis on “Physics, Computer science and Complex Networks”, is an option of Master 2 that is part of the Masters of Physics (Sciences de la Matière), Computer Science (Informatique Fondamentale) and Biology (Biosciences) organised by the ENS of Lyon and University Lyon 1, so as to provide an innovative training for students who are interested in the interdisciplinary research of complex networks and modeling of complex systems.

This program maintains a balance between different disciplines by combining courses from the fields of biology, computer science, mathematics, physics and sociology. Students from all of these disciplines are welcome to participate; the student will follow both the ”Complex Systems” program and part of their own M2: Computer Science, Physics, or Bioscience (please contact the people responsible of the program for more details).

The inscriptions to the program has to be made by following the procedure of the ENS de Lyon webpage : Follow the online procedure for admission in Master et the ENS of Lyon (or the University of Lyon 1). For the ENS of Lyon, this is explained here in french (for student already in France) or here: admission at ENS de Lyon (in english) for others. Be attentive to the deadlines. Also, please contact Pierre Borgnat and Márton Karsai, the two people in charge this part of Master, so that we are aware of the application. 

 The program puts a special focus on the theory and modelling of complex networks and provides special training in data-driven research. In the end of the program students will receive a degree supplement assigned in their original master degree. All courses are given in English (optionally in French) for 4 or 6 ECTS during the fall between September and February. For a successful validation the participating students are required to collect 30 ECTS during the first semester, and 30 ECTS for the second semester, from the following offer:

Mandatory courses

  • Introduction to Computer Science*  (N. Trotignon, S. Thomassé) - 28h + 8h TD, 6 ECTS (includes Epistemology of the modeling of complex systems, S. Franceschelli)
  • Introduction to Statistical Physics* (N. Garnier, B. Pascal) - 28h + 8h TD, 6 ECTS (includes Epistemology of the modeling of complex systems, S. Franceschelli)
  • Complex Networks (**CS CR 15 CS course), (R. Cazabet, L. Pacini) - 24h + 6h TD, 4 ECTS
  • Dynamical processes and networks, (P. Borgnat, T. Nguyen-The) - 20h + 8h TD, 4 ECTS

* mandatory course for students who are not from the same discipline (and that cannot be validated fro students of the same discipline)

Research courses

  • Data analysis and processing for networks, N. Pustelnik, P. Borgnat - 18h, 3 ECTS
  • Modeling in biology and medecin, L. Pujo-Menjouet, B. Audit, O. Gandrillon - 18h, 3ECTS
  • Modeling of Social Systems, P. Jensen - 18h, 3ECTS
  • Other research lectures in Master 2 in Computer Science Master or Physics

Research Internship

The students have to follow a research internship of at least 16 or 20 weeks, during the second semester and it will count as 18 or 30 ECTS (validated by a written report and an oral presentation).
