Guido Tana (Italy, 1990) is FCT Junior Researcher at the Institute of Philosophy of the NOVA University Lisbon (IFILNOVA). He holds a Master’s Degree from the University of Pavia (2014) and a Ph.D from the University of Edinburgh (2021).
He works in contemporary and social epistemology, philosophy of science, and has related interests in the History of Philosophy. His research focuses on the following topics: Justification, Evidence, Skepticism, Dogmatism, Scientific Disagreement, Trust, Epistemic Authority, Recognition, Non-Ideal Epistemology, Underdetermination, Rule-Following, Theory-Change, Understanding, and Epistemic Division of Labor. In the History of Philosophy, his interests pertain to the later Wittgenstein, German Idealism (particularly Hegel), the Pittsburgh School (Sellars, Brandom, McDowell), Pyrrhonism, Descartes, and Feyerabend.
His work has been published in international journals, such as Analytic Philosophy, Theoria, and Grazer Philosophische Studien.
His current project at IFILNOVA focuses on the social determination of epistemic justification, with a focus on how epistemically significant evidence is a product of shared, intersubjective activities. In the past, he has been a postdoctoral researcher at IUSS Pavia, working with Professor Silvia De Toffoli on Disagreements in Science, and at IFILNOVA, where he has worked on Epistemic Injustice and argumentation, as well as on Mary Hesse’s post-empiricist epistemology. He has also been visiting researcher in 2024 and 2025 at the Technische Universität Berlin at the chair of Professor Axel Gelfert, and twice DAAD Stipendiat at the Universität Leipzig (2018/19) and at the Freie Universität Berlin (2013/14).
