I am a PhD student in philosophy at the University of Geneva within the SNSF-funded project The Metaphysics of Time and its Occupants, under the supervision of Fabrice Correia. I am also a member of eidos, the Genevan centre for metaphysics.

I work primarily in analytic metaphysics, and mainly on time and on money.

These interests have naturally led my research intersect with the philosophy of science, mostly the philosophy of physics and the philosophy of economics.

I have taught logic, philosophy of language and metaphysics in Geneva and Neuchâtel.

I spent a year of my PhD in New York (NYU and Rutgers, 2018-19). Before starting in Geneva in 2017, I was a PhD student at the University of Neuchâtel (2015-17, within the same project). Before still, I completed a Master in Philosophy (2012-15, Geneva) and a Bachelor in Philosophy and Cultural Anthropology (2009-12, Geneva and Neuchâtel).


Philosophy of Time

In the philosophy of time, I mostly work on metaphysical issues surrounding persistence, temporal existence and temporal ontology, and change and tense. These topics naturally bring to related considerations in the metaphysics of objects more generally, with a focus on mereology and location, and the philosophy of spacetime physics.

My PhD dissertation – entitled All Things Must Pass: Temporal Existence in a Spatiotemporal World – is about the persistence of ordinary objects over time and their survival through change in a world governed by relativistic spacetime physics. I propose a new framework to think about the problem of persistence and build persistence theories, and I defend a form of exdurantism view according to which ordinary objects persist in virtues of having proxies located at relevant regions of spacetime.

Social Ontology

I currently work on two different problems in social ontology. One is the ontology of economic entities, in particular money. I defend that money is always a form of deontic power – a normative property of social agents – and never a concrete object. In this context, I also dabble in the philosophy of economics.

The other is the nature of incantatives, a novel class of speech acts intimately tied to collective emotions and to the constitution of some social groups (this is joint work with Constant Bonard).

Other interests

In metaphysics, my other interests include identity, modality, fundamentality and explanation, levels of description, and fineness of grain. In the philosophy of physics, they concern the foundation and interpretation of quantum mechanics. I also have a strong interest for formal methods in metaphysics and the philosophy of language, and a passing interest for normative questions in epistemology.


I have been an active member of Cooloque, an association of young Swiss researchers in the humanities devoted to the study of notions like coolchilllose and yolo. We organized public outreach events in Romandy between 2011 and 2016, and self-published their proceedings in various formats.

    While different kinds of speech acts can contribute to the construction of social reality, contemporary philosophers have focused on declarations. We defend that there is another kind of speech act that is operative in the construction and the maintenance of social facts: the incantatives. The main function of incantatives is to express and generate collective emotions(and other evaluative attitudes) about shared values (or other normative objects), and to thus contribute to the existence of social groups such as communities.
