I am an assistant researcher at CIUHCT (ULisboa) funded by the CEEC program of FCT (2021-2026) and an invited assistant professor in History and Philosophy of Science (ULisboa). As a historian of science my aim is to shed light on the diversity and dynamics of "mathematical cultures" in different social contexts of the middle ages and early modern Europe by studying the role of diagrams and astronomical and mathematical instruments. I combine skills in methods of cultural history, in mathematical sciences, philological and codicological expertise, and experience in material culture studies. EDUCATION: In Switzerland and France, I obtained an MA in Physics and then a PhD in Epistemology and History of Science (très honorable, avec felicitations du jury, 2006). RESEARCH: My research contributed to the history of mathematics; in particular I developed an original study method for preserved scientific instruments. My work experience improved my skills in philology, manuscript and material culture studies, and outreach. I am grooming international networks of peers. Since my PhD I conducted four post-doc projects and I have collaborated in 15 (fifteen) projects as a member. Since 2015 I have had the following roles: Post-doc, ERC funded project ALFA, to analyze the visual and material culture of mathematical astronomy in the late medieval and early modern period, France, 2019-2021. Scientific collaborator, to lead, with senior curator Korey, a team of museum education staff, media specialists, and conservation experts and to develop a novel approach of public engagement. Germany, 2016-2017, funding from KSB Germany (ca. 130 kEuro). Researcher, to bring ancient astronomy skills to a team of historians, horological experts and curators of the project "Deus ex Machina", 2014-2015, funding from Museum Research Foundation for 2015-2016 (ca. 50 kEuro). Independent researcher, to conduct a 6-month research, funding from Eisinga foundation, Netherlands, in 2014. (ca. 20 kEuro) TEACHING, OUTREACH: Since 2015, I have taught seminars in chapters of historiography of science, history of mathematics, and instrument studies in Portugal, France and Canada. I assist in teaching an undergraduate course at the Department of History and Philosophy of Science, 2023. I am currently co-coaching five PhD students in various roles. I developed a research-based exhibition at a major public museum of Germany (2016-2017). I am creating spaces for debate within the host institution CIUHCT (co-org. Seminar of Ancient Astronomy and the Journal Club reading group). PUBLICATIONS, ORGANIZING: Publications (many in co-authorship) since 2019 (4 books, 7 journal articles, 8 book chapters) reflect my internationalization and commitment to collaboration. During the same time, I gave 50 papers, mainly at international congresses, and I organised ten international workshops: supported by ALFA, 2-days / 8 scholars workshop, 2021. with Korey and Gaulke, 3-days / 25 scholars workshop, 2020 (funding Thyssen foundation, ca. 14 kEuro). with Dijkstra, 2-days / 12 scholars workshop, 2019. (funding Eise Eisinga Foundation, ca. 10 kEuro). ADVISING: I acted as a scientific advisor to an museum4punkt0 project (2021) at one of the major German public museums (SKD). REFEREEING: I work as a peer-reviewer for editors (Brill), and journals (e.g. Centaurus, Journal for the History of Astronomy), and served on scientific committees of several international congresses (SIC, ENHCT). KEYNOTES: at 1st Meeting of Young Scholars, European Society of History of Science, Paris (France), 2019. at Joint Conference of the Atlantic Medieval Association & AMEM Group, Sackville, 2018. APPOINTMENTS: Adjunct Professor, Faculty of Arts, Mount Allison University (Canada), 2017-2020. Museum Fellow, Kulturstiftung des Bundes (Germany), 2016-2017. Afilié of SYRTE (History of Astronomy group), Observatoire de Paris, 2022- . Book Review Editor Journal HoST, 2020-2026.
