I recently (November 2020) completed a PhD in philosophy and epistemology at the University of Paris 1 Panthéon-Sorbonne, where I wrote a doctoral thesis under the direction of Dr Philippe Huneman, entitled "The formalisation of evolutionary theory: a philosophical and historical approach". Furthermore, under the supervision of Professor Christophe Malaterre at the University of Quebec in Montreal, I completed a postdoctoral research project that focused on the history of biometry through the computational analysis of the archives of the journal Biometrika. Before starting my PhD programme, I graduated from the Philosophy Department of the École Normale Supérieure de Paris as a foreign student fellow ("Sélection internationale"), under the tutorship of Professor Claude Debru and Professor Mathias Girel. During my PhD, I conducted extensive research on the rational reconstruction of scientific theories by focusing on the theory of evolution and adopting an integrated historical and epistemological approach. In the first part of my doctoral thesis, I spelt out a definition of the notion of "conceptual framework" based on Rudolf Carnap's version of the received or syntactic view of scientific theories. In the second part, I applied this definition to the case of the Modern Evolutionary Synthesis in order to clarify its structure and content precisely as a conceptual framework. In both cases, I elucidated the meaning of the concepts I was analysing by situating them in their historical and intellectual context and paid considerable attention to problems arising from the validation of scientific knowledge, especially in evolutionary biology. For instance, on the one hand, I analysed the relationship between the logical-positivistic concept of "empirical basis" and the syntactic view of scientific theories, thereby highlighting how the problem of devising new validation practices shaped the philosophy of science after the crisis of late 19th-century mechanistic philosophies. On the other hand, I shed light on the connections between the formal and mathematical structure of the Modern Evolutionary Synthesis' conceptual framework, as exemplified, to name only one example, by fitness landscape models, and what I called the "empirical structure" of this same framework, i.e. how it allows representing the various facets of evolution as a natural process. By doing so, I showcased the centrality of questions related to the validation of Darwin's theory for understanding both the history and epistemological status of evolutionary biology. Therefore, my doctoral thesis demonstrates my ability and willingness to critically engage with problems arising from how evaluative categories and practices have been developed and assessed across diverse philosophical and scientific contexts. Moreover, prior to starting my PhD studies, I completed a research stay at the University of Bielefeld, where I wrote a master thesis on the relations between Friedrich Nietzsche and Georges Canguilhem, and a research internship at the Max Planck Institute for Mathematics in the Sciences in Leipzig, where I worked on a computational model of DNA translation and transcription mechanisms. Both experiences allowed me to perfect my proficiency in German and attest to my capacity to conduct research work in a German-speaking environment. Furthermore, I guest-edited, in collaboration with Professor Tim Lewens, an interdisciplinary special issue of the journal Studies in History and Philosophy of Science Part C devoted to the interpretations of R. A. Fisher's "Fundamental Theorem of Natural Selection" and Alan Grafen's "Formal Darwinism Project", where I published an article. I also gave various oral presentations at highly selective English-speaking conferences, such as those organised by the European Philosophy of Science Association (EPSA) or the British Society for the History of Science.
