I am currently a Ramón y Cajal fellow at ​the Department of Logic and Theoretical Philosophy of the Complutense University of Madrid.

I work mainly in metaphysics. My main research interests lie in the philosophy of time, inter-level metaphysics, and mereology.

Among other topics, I am particularly interested in the debate on the reality of temporal passage, ‘Fine’s McTaggart’, fragmentalism, the ‘grounding objection’ to presentism (and other A-theories of time), the relation between metaphysical grounding and necessity, and the idea that wholes are identical to their parts taken together (aka ‘Composition as Identity’).

I’ve also recently become interested in the metaphysics of aperitifs (and theories of location).

Before coming to Madrid, I was a Research Fellow and a member of the Phlox Group at the University of Hamburg,  a Post-Doctoral Research Fellow and a senior member of the LOGOS Research Group at the University of Barcelona (2015-2017), and a Post-Doctoral Research Fellow at the Instituto de Investigaciones Filosóficas at the Universidad Nacional y Autónoma de México (UNAM) in Mexico City (2013-2015).

I obtained my PhD in Philosophy in October 2012 from the University of Nottingham. My supervisor was Prof. Stefano Predelli.

According to PhilPeople, I am among the top 1% most cited authors in metaphysics in the past 5 years.

Here are my Google Scholar, PhilPapers, and Academia.edu pages.
