Julien Chopin is an experimentalist and a physicist interested in pattern formation and complex dynamics of soft materials. These include elastic sheets, filaments, granular materials, soft polymers, ...

Below, a list of scientific themes he is interested in :

  1. Elastic and viscous singularities
  2. Fracture and wetting of heterogeneous solids
  3. Buckling, wrinkling, and creasing of elastic ribbons and filaments
  4. Fibrillation and cavitation in soft matter
  5. Pattern formation in granular materials
