The FOIE GRAS project is an European Training Network (ETN) receiving funding from the H2020 Marie Sklodowska Curie Actions. This network focuses on the study of the Bioenergetic Remodelling in the Pathophysiology and Treatment of Non-Alcoholic Fatty Liver Disease (NAFLD). This is a blog where the 13 PhD students belonging to the network share our personal experiences and discuss the professional challenges and privileges of being an Early Stage Researcher (ESR).
