Co-supervised thesis

A thesis can be supervised by several people. Certain rules must nevertheless be satisfied:a thesis director ONLY be the principal director of the thesis in the doctoral school to which they are attached. They can be co-supervisor in any doctoral school. The rule in force within ED PHAST is that the accumulation of management responsibilities  as the main supervisor and co-management cannot exceed 300% (a thesis as sole supervisor counts for 100%). In addition, a minimum commitment is required (co-direction of less than 20% makes little sense).
