Head of the group

ChrisWuthrichChristian Wüthrich is Associate Professor of Philosophy at the University of Geneva. Christian’s philosophical interests most prominently include foundational issues in physics, particularly in classical general relativity and quantum gravity. Of course, he also gets excited about the implications of philosophy of physics for general philosophy of science and metaphysics. More specifically, he enjoys thinking about issues such as space and time, persistence, laws of nature, determinism, and causation.

JoshuaJoshua Babic is a PhD student supervised by Fabrice Correia. He is a board member of the Swiss Graduate Society for Logic and Philosophy of Science. His interests lie in logic, metaphysics and the philosophy of physics.


ClaudioClaudio Calosi is an SNF Assistant Professor at the University of Geneva, Department of Philosophy. He is the leader of the SNF-funded project, Metaphysics of Quantum Objects, which will run for 5 years. He works mainly in Analytic Metaphysics and Philosophy of Physics. The core of his research—or so he would say—concerns the application of formal methods (e.g. mereology, topology, dependence, location) to broad philosophical issues such as identity, composition, dependence, and fundamentality. When he is not doing philosophy he is reading, or watching Roger Federer and the Pittsburgh Steelers.

enricocintiEnrico Cinti is a PhD student at the University of Geneva (supervisor: Christian Wüthrich) and the University of Urbino (supervisor: Vincenzo Fano). He works mainly on the philosophy of physics, with a particular focus on quantum gravity and cosmology. In particular, his PhD project concerns the implications of the firewall paradox and its resolution within the ER=EPR conjecture for our metaphysical picture of the world, in particular with regards to entanglement and emergence. Outside of this, he enjoys thinking about broader topics in metaphysics and philosophy of science, such as space and time, laws, modality, scientific realism, and the relation between mathematics, physics and the world.


Lorenzo Cocco is a PhD student working on Field’s Program for General Relativity under the supervision of Chris Wüthrich (Geneva) and Vincent Lam (Bern).


SaakshiSaakshi Dulani, is a Fulbright-Swiss Government Excellence Scholar at the University of Geneva. For her PhD dissertation, she aims to precisify the role of information in the foundations of physics, focusing on the Black Hole Information Paradox and the Holographic Principle. In May 2019, she graduated from Columbia University’s Philosophical Foundations of Physics master’s program. Her broader research interests include naturalized metaphysics, epistemology of quantum gravity, theory choice, and values in science.


Stefano Furlan, conducting his Ph.D. studies between the University of Geneva (supervisor: Christian Wüthrich) and the MPIWG in Berlin (co-supervisor: Alexander Blum; “Historical Epistemology of the Final Theory Program”). His dissertation work is mainly focused on the conceptual and historical roots of quantum gravity, with a special emphasis on J.A. Wheeler, his private notebooks and the “parallel” work on the nature of singularities made by Zeldovich and Novikov in the Soviet Union. More specific issues concern a critical analysis of non-empirical arguments in contemporary physics; the way analogies are treated in secondary literature and how this is intertwined with Wheeler’s visual style; how the latter, together with his notion of history, contributed to shape his Princeton school of general relativity and, thus, the way in which related problems were (and still are) faced; the path that, from general relativity and quantum mechanics, led Wheeler to his pioneering ideas about the foundational role of information and its philosophical repercussions.

ManusManus Visser  is a postdoc at the Department of Applied Mathematics and Theoretical Physics in Cambridge.


davidschroerenDavid Schroeren is a postdoctoral fellow in philosophy on the project The Metaphysics of Quantum Objects at the University of Geneva with principal research interests at the intersection of philosophy of physics and metaphysics. His current work develops a fairly general metaphysical framework for modern physics that underwrites the vision that symmetries of the world are fundamental, whereas the material constituents of the world (such as particles and fields) are ontologically derivative of them.


Lucy JamesLucy James is a PhD student at the University of Bristol, supervised by James Ladyman and Karim Thébault. She is currently undertaking a pre-doctoral fellowship funded by the John Templeton Foundation at the University of Geneva, where she is supervised by Christian Wuthrich. She holds a BSc in mathematics from Brunel University and an MA in philosophy of mathematics from the University of Bristol. Her PhD thesis, ‘Has Metaphysics Done Its Time?’, investigates metaphysical questions about time and locality by studying contemporary physical theories. The thesis asks whether this methodology, inspired by naturalised metaphysics, might be too constraining when considering certain kinds of metaphysical problems. Her research interests are broad, tending to cluster around physics, applied mathematics, and metaphysics.


Alberto_largeAlberto Corti was a PhD student in philosophy and metaphysics of science at the University of Urbino (supervisor: Vincenzo Fano) in co-tutorship with the University of Geneva (supervisor: Christian Wüthrich), working on his PhD project “the metaphysics of quantum indeterminacy” where he investigated the applicability of metaphysical indeterminacy accounts to quantum phenomena. Before, he obtained both his bachelor and master in philosophy at the State University of Milan and he spent six months at the master of arts in philosophy at the Università della Svizzera Italiana of Lugano. His main interests lies in metaphysics (in particular persistence through time and indeterminacy), philosophy of science (debate on scientific realism and foundations of quantum mechanics) and their combination i.e. metaphysics of physics/naturalized metaphysics


SalimSalim Hirèche‘s main philosophical interests are in metaphysics – in particular, in questions at the intersection of metaphysics and the philosophy of science (laws of nature, natural necessity, causation, dispositions, explanation). After completing his PhD at the University of Geneva, he obtained a Swiss National Science Foundation (SNF) postdoc mobility grant to work on the modality of causation and grounding at the Universities of Oxford and Glasgow. He joined the Symmetry Group in September 2019, as part of the SNF-funded project “To and Fro: Scientific Metaphysics at Physics’s Frontiers”, led by Christian Wüthrich; his current research mainly concerns the existence of natural entities and its modal status, and relies on insights from both metaphysics and physical theories.

He works on a project titled “The Prospects of Naturalized Metaphysics” where he investigate the role of physics in metaphysics, and attempt to assess to what degree metaphysics should be informed by and founded in physics. He is also engaged in research on foundational issues in high energy physics, particularly on the nature of spacetime in the light of the AdS/CFT correspondence and on the metaphysical implications holographic relation between entanglement and spacetime.
