Every two years, the National Committee for Logic, History and Philosophy of Science (NCLHPhS) organizes the Young Researchers Days. Through open call proposals, we typically invite about 20 young researchers working in Belgium in these three fields, to present their work and to engage in communal question rounds. This edition is already the ninth instalment of this interdisciplinary meeting of young researchers in the fields of logic, history and philosophy of science. The Young Researcher Days offer an unusually interdisciplinary opportunity for young researchers, i.e. PhD students and postdocs to present their work to a larger community of emerging and established scholars, and to explore how their research can be engaging across disciplinary boundaries.Â
