I work mainly in metaphysics. My main research interests lie in 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 Hamburg, I was a Post-Doctoral Research Fellow and a senior member of the LOGOS Research Group at the University of Barcelona (2015-2017) as well as 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).
According to PhilPeople, I am among the top 2% most cited authors in metaphysics in the past 5 years.
