I am a historian of philosophy specialized in early modern philosophy. My research focuses on 17th-C. philosophy and Baruch Spinoza in particular.

I am currently a Postdoctoral Researcher at Louisiana State University. I am also a chercheur associé of the LLCP (Paris VIII) and a member of the American Philosophical Association's Committee for International Cooperation.

In the fall of 2026 I will begin a position as Assistant Professor of Philosophy at the University of South Florida.

I recently pursued my research as a Solmsen Fellow (2024-2025) at the Institute for Research in the Humanities, University of Wisconsin - Madison. The Solmsen supported my ongoing project: Spinoza and the Philosophy of War.

Another recent project of mine was co-editing The Edinburgh Critical History of Early Modern and Enlightenment Philosophy (Edinburgh University Press, 2025). I am co-founder of the research seminar Spinoza à Paris 8 and co-editor of Spinoza in Twenty-First Century American and French Philosophy (Bloomsbury Academic, 2019).

I hold a PhD and MA from the University of Paris VIII. I hold a BA from Cornell University.
