On the 4th of October, the 2019 edition of Lof der Geneeskunst took place in De Doelen in Rotterdam. This year’s theme was ‘Customised medicine; small scale, large impact’ (‘Maatwerk in de geneeskunde; kleine schaal, grote impact’). We visited the symposium with the board and recognised two familiar faces; Prof. Marileen Dogterom and Dr. Roland Kanaar both teach courses in the Nanobiology programme. They showed the audience how research into molecules helps us to understand diseases, improve diagnostics and treat patients. Their speeches were interspersed with dance, acrobatics and music by students of Codarts, the international college of the arts.
