Job Description
Missions
The postdoctoral researcher will investigate out-of-equilibrium dynamics in high-dimensional disordered systems (including models relevant to machine learning and optimization) by characterizing the fixed points (metastable states, attractors) of the governing dynamical equations and the pathways connecting them. The focus will be on the geometry of high-dimensional random landscapes: identifying atypical, yet not rare, clusters of metastable states and low-energy pathways between them, and determining when and how constrained dynamical trajectories select these structures over more typical ones.
Activity
The postdoc will (a) contribute to the research tasks, using both analytical and numerical methods, contributing to numerical validation of analytical predictions where relevant; (b) write up results for publication and present them at group meetings, workshops, and conferences; (c) co-supervise a Master 2 intern on the research topics connected to the project.
Your Profil
Skills
Candidates should hold a recent PhD in theoretical/statistical physics, applied mathematics, or a related quantitative field. A background in the theory of high-dimensional systems and hands-on expertise in the technical toolkit of disordered systems (replica methods, dynamical mean-field theory) are appreciated. Experience with models and questions arising in machine learning theory (loss landscapes, generalization, high-dimensional optimization) is a strong asset, given the project's connections to that area.
Your Work Environment
The position is hosted at LPTMS (Laboratoire de Physique Théorique et Modèles Statistiques), CNRS / Université Paris-Saclay. Valentina Ros will directly supervise the postdoc. The postdoc will likely interact closely with the collaborators in the Paris Saclay area, such as P. Urbani (IPhT), A. Rosso (LPTMS), C. Furtlehner, S. Chibbaro (LISN). The postdoc will have dedicated funding for conferences and computing equipment.
Constraints and risks
The position primarily involves analytical and, to a lesser extent, numerical work, with no specific physical or safety constraints. Given the theoretical and exploratory nature of some of the research tasks, some flexibility and tolerance for open-ended, iterative research directions is expected.
