Students

We are always happy to accept students from different backgrounds (physics, mathematics, social sciences) who would be interested in complex socio-economic systems. Having good skills in programming or mathematics would be extremely helpful as well as having a good grasp of statistical physics or social sciences, but these are surely not mandatory as with proper determination and with enough effort anything can be learnt.

If you are interested, feel free to contact us. We will try to schedule a meeting to find a problem you could tackle.
