2 Postdoc positions opening

  • 2 postdoctoral positions opening in my group in IPhT, CEA Saclay (starting September 2017) on statistical mechanics of neural networks and representation learning. Interested candidates are welcome to contact me with their CV starting from now. More detailed call is for dowload here.

Events not to be missed:

  • February 27 - March 3, 2017 we organize a workshop in Les Houches Statistical physics, Learning, Inference and Networks . We have an amazing list of speakers. Register and come to discuss great science and ski.

  • July 3 - 28, 2017 we organize Boulder Summer School on Frustrated and Disordered Systems. If you want to learn about the replica method, cavity method and its use in studied of glasses and other systems, such as inference or machine learning, this is the place you should be this coming July. Register before January 15, 2017.

  • Check the schedule of the Golosino seminar to taste the best pizza and to listen to the best talks on applications of statistical physics in Paris.

  • Save in your calendars and stay tuned for 2nd edition of 'Spin Glass and Beyond' in Cargese (20 - 31 August, 2018).

I am interested in statistical physics of complex systems

Statistical physics has been developed in order to study the collective behavior of many-particle systems. Traditionally, it aims at understanding physical materials composed out of a large number of molecules or other small constituents of matter. Probability theory is combined with microscopic rules (interactions) to describe the collective properties such as the heat capacity, the density or various phase transitions. Motivated by the demands of our developing society, today's science needs to understand many other systems composed of a large number of interacting elements. To give few examples these elements may be: agents selling and buying items on the market, genes regulating the cell functions or dys-functions, the network of power lines delivering energy to our homes, Boolean variables in logical formulas designed to verify functions of electronic devices, planes landing and departing in a large international airport, or the network of neurons in our brain that allows one to read and comprehend this very text.

The experience collected over decades by physicists in the studies of matter needs to be exploited in order to understand, or predict, new relations between the microscopic (local) and macroscopic (global) properties of these complex systems. Particularly handy in this task are techniques developed in studies of disordered systems such as spin glasses, structural glasses, interfaces pinned by impurities, polymer networks or grains of sand. This is because the above mentioned complex systems are very rarely ordered, homogeneous or strongly symmetric, often they are not even embedded in an Euclidean space. This is the general line of research that makes me passionate and that I develop.
