LabEx Cell(n)Scale

Project grants

The purpose of Project grants is to initiate research projects in the scope of the LabEx Cell(n)Scale scientific objectives, at the interface between physics/chemistry and biology. This program aims at supporting innovative early stage projects, notably initiated by young researchers, acting as a lever to develop new, original ideas further and serve as a lever to obtain additional funding. Grant of 5 to 20k€ support equipment acquisition and/or lab functioning. Project grants can be coupled with postdoctoral fellowships, but will be evaluated independently based on established criteria. Project leaders will be asked to present the progress of their project at a LabEx seminar one year after its start.
