Edith Heard is a Professor at the Collège de France and the Director General of Europe’s “CERN for biologists”, the European Molecular Biology Lab (EMBL). In this episode, Edith explains how she gets ideas when she’s out of her comfort zone and being challenged, and how in her youth she would go to the piano whenever her brain needed time to solve a hard math problem. She emphasizes how much she profited from the “naive optimism” in science in the US – compared to the much more rigid, historical European approach. She discusses with us the importance of deep knowledge about your research subject, paired with the humbleness of feeling you don’t know enough. And then she tells us how she tucks away questions in a drawer until methods become available to answer them. For more information on Night Science, visit https://www.biomedcentral.com/collections/night-science .
