Ambassador Delegate for Science, Technology and Innovation, former Director General and then President of the CNRS, Catherine Bréchignac is Honorary Perpetual Secretary of the French Academy of Sciences. It is in her deep convictions to maintain a balance between her various activities: purely scientific research activity as a nanosciences physicist, activity as a scientific manager as Director General then President of the CNRS, activity in scientific diplomacy as Ambassador. In spite of the important scientific responsibilities she has assumed, she has always been able to keep a scientific activity in the laboratory, then in writing books on the scientific approach, in order to explain how science is built and how scientific thought develops over the years. It is this passion for science, to defend and promote it in France and internationally, that led successive governments to appoint Catherine Bréchignac and then to confirm her as Delegate Ambassador for Science, Technology and Innovation. The author of numerous books and recipient of numerous awards, she was raised to the rank of Grand Officer in the Order of the Legion of Honor.

Currently a research director in Computer Science at CNRS (Paris University) and member of the French Academy of Sciences, Claire Mathieu has worked as a CNRS researcher at ENS-Lyon and as a professor in various institutions: Collège de France, École normale supérieure ("attached" professor), Paris-Sud University, École polytechnique, Brown University (USA). Her research area concerns algorithms, with a focus on the design of algorithms to find near-optimal solutions to problems that are hard to solve exactly. Recently, she has been interested in modeling social networks, analyzing stable marriage algorithms, reconstructing hidden graphs, and epidemic simulation. She was awarded the CNRS Silver medal (2019).

Leila Schneps received her B.A. at Harvard University in 1983, and then moved to France to pursue her Ph.D. in mathematics at the University of Paris, where she later became a researcher at the French Center for Scientific Research. Although her main area is pure mathematics, she became interested some years ago in the way in which mathematics is used in criminal trials and medical diagnostics, two areas in which a close examination raised major concerns about serious errors being made due to misunderstandings and misuses of probabilities. Together with Coralie Colmez, she published a book called Math on Trial (Basic Books, 2013) detailing 12 cases of mathematical errors leading to miscarriages of justice from the end of the 19th century to today. Since then, she has become involved in working with the French police on efforts to bring Bayesian networks and artificial intelligence into the crime investigation community, and also in publicizing the problems with the current medical practice of rigidly diagnosing shaken baby syndrome in the presence of certain symptoms based on a faulty understanding of the results of certain statistical studies, leading to the arrest of parents and the breaking up of families.

Héloïse Brezillon is a phd student in creative writing, a poetess and a science-fiction writer. Regarding theory, she's studying what she calls "sound science-fiction", an emerging genre combining imaginary literature and sound experimentations. As for her creative writing practice, it is full of obsessions : the body as a territory, feminine intimacy, how we deal with our ecosystems and power. Her approach is both stamped by her political radicality and her sensitivity about the flesh and the world. She also gives creative writing workshops at universities, schools and differents social structures, because she believes that it's possible to generate poetry and imagination in everybody.

Louise Marc is a PhD-candidate at the University hospital of Zurich in the department of Medical Physics, more concretely in cancer treatment by radiotherapy. During her Bachelor studies in Physics at Technische Universität Darmstadt (Germany), an exchange year at École Centrale Paris followed by a Master in Applied Physics at École Polytechnique Fédérale de Lausanne (Switzerland), she could get in touch with different domains at the interface between physics and medicine. Determined to improve and innovate in the health field with a physicist's approach, she is interested in interdisciplinary questions. Her current research is about how to improve the conventional radiotherapy, i.e. photontherapy, in terms of precision through the use of protons. The so-called proton therapy is more costly but generally much more precise. Thus, it potentially represents in combination with the use of photons, a general improvement for radiotherapy in clinics. Louise is passionated about music, and lives her passion particularly by playing the piano since her childhood.

During his studies at École Centrale Paris (now called CentraleSupélec), Valentin pursued a 3-year research project in plasma physics applied to future low-carbon technologies and joined the LIGO collaboration for 6 months. Now a graduate, he is moving towards more abstract research in fundamental mathematics and is currently in his first year of a PhD in Probability at the University of Paris-Sud and the CEA of Paris-Saclay. His subject is the study of the spectral properties of a certain type of random matrices, which are of interest both to mathematicians and theoretical physicists, but also ultimately to the machine learning or telecommunications industry. Passionate about science, in 2018 he coordinated the organization of a large-scale student scientific symposium (the first edition of the CentraleSupélec Scientific Symposium), and during his doctorate he leads scientific workshops for primary and secondary school students at the Maison d'Initiation et de Sensibilisation aux Sciences (MISS) in Paris-Saclay. Today his interest lies in the democratizing critical thinking and a philosophical approach to our relationship to knowledge.

II did my training in psychiatry and psychotherapy with special interest in psychoanalysis in the PLK Weissenau, the university hospital of the Universitaet Ulm in Germany. I was lucky to establish myself in the profession during a time of new therapeutic possibilities, a situation for which I was and remain very grateful to my teachers and colleagues. I also work today in couple therapy, having been trained by C. Gammer in family therapy. Under the guidance of Prof. Hole, I have taught hypnosis to students (medical doctors) of psychotherapy in Germany, later in Zurich, at the Psychiatric University Hospital Burghoelzli. For some years, I have been working in Paris as a practitioner in my private office; in addictologyI am attached to the HEGP/AP-HP. When treating my psychiatric and psychotherapeutic patients, I also include behavioural therapy (e.g. DBT, Scheme Therapy).

Xavier Emmanuelli graduated as a doctor of merchant medicine and joined the maritime courier. Then he became a general practitioner at the Coal Basin of the Freyming-Merlebach Mines. At the same time, he became part of the founding team of Médecins Sans Frontières (MSF), with a desire to create an international emergency relief effort. In parallel, from 1972 to 1975, he was the assistant to Professor Pierre Huguenard for the creation and development of SAMU 94, one of the first Emergency Medical Aid Services. As an anesthesiologist and reanimator. From 1992 to 1995 Xavier Emmanuelli was a hospital practitioner at the Care and Accommodation Center at the Nanterre hospital. He described a new clinical approach to social exclusion observed during consultations with the homeless. He then imagined a social SAMU like the medical SAMU in order to take charge of people in situations of exclusion. From 1995 to 1997, he was appointed Secretary of State for Emergency Humanitarian Action by President Jacques Chirac. In 1998, he also founded the Samusocial International, in order to address the high levels of exclusion amongst homeless people in big cities of the world.
