The memory of humanity relies on the ability to manage increasingly large amounts of data, over periods of time ranging from a few years to several centuries. In order to respond to the exponential increase of the digital universe, data centers consume more and more energy and generate more and more heat. In addition to the digital sobriety we need to promote, it turns out that a significant part of the data we create is actually "cold" or rarely accessed. Current tools are no longer sufficient and it is necessary to consider game-changing solutions that can become quickly operational. Inspired by the way information is being stored in nature, one of the most promising solutions could come from the use of DNA as a digital storage medium. A graduate engineer from the University of Patras in Greece, Melpomeni Dimopoulou combines her passion for computer science and biology. As a post-doctoral researcher at the I3S laboratory (Université Côte d'Azur and CNRS) in Sophia-Antipolis, France, her research areas focus on the storage of digital data on DNA. In 2019, she won the final of the "Thesis in 180 Seconds" competition of the Université Côte d'Azur Chapter as well as one of the best student paper prizes at the EUSIPCO (European Signal Processing Conference). In 2021, she received two innovation prizes awarded by Bpifrance (Public French Investment Bank) and CNRS (French National Centre for Scientific Research). She also won the Award L'Oréal-UNESCO Young Talents France for Women in Science. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
