This Monday 27 April marks the partial reopening of UNIL's laboratories, as announced by the authorities in mid-April. This is good news for the scientific community, but it should be tempered: the restart will be partial, it will only concern research activities requiring a physical presence in the UNIL buildings and it may be called into question depending on the evolution of the health situation. The return of researchers to the campus will also have to comply with strict conditions set out in a note approved by the Rectorate on Friday 24 April, on the proposal of UniSEP and a working group of the Faculties under the direction of Vice-Rector François Bussy.
