In3 MSCA project PhD students discuss why they did a PhD and whether they were happy with the outcome. 

The in3 project is funded by the EU's Marie Sklodowska-Curie Action - Innovative Training Network (MSCA-ITN for short) that aims to drive the synergistic development and utilisation of in vitro and in silico tools for human chemical and nanomaterial (NM) safety assessment. https://ec.europa.eu/research/mariecurieactions/
