Among the doctoral students surveyed, 45% prefer working from home, against 7.4% who reported they always conducted research within their laboratories. While a minority of them perform research in other areas, such as public spaces (Wi-Fi). Indeed, the place of research is a major factor in the quality and nature of the tools used, the social and pedagogical relationship (with colleagues and thesis directors), as well as the mobilisation of knowledge and expertise throughout the research process.
