I am a post-doctoral researcher at the Center for Brain and Cognition (UPF). My research aims to understand the scope of infants and children’s social cognition, in particular how they represent the main properties of social relationships and resource distribution.

In parallel, I coordinate and teach several Psychology courses at the Department of Experimental and Health Sciences (UPF).

Previously, I graduated in Psychology and specialized on Neuroscience, obtaining my PhD title in 2018 at the Universitat Pompeu Fabra (Spain) after two stays abroad at Central European University (Hungary) and Cornell University (United States). My thesis focused on the influence of social hierarchies on infant's learning and was supervised by Núria Sebastián-Gallés. 

Later, I was  working with Olivier Mascaro on a project financed by the Fyssen Foundation investigating the representation of leader-follower relations during infancy. The project was developed at the Institute for Cognitive Sciences - Marc Jeannerod UMR 5304 (Centre National de la Recherche Scientifique, Lyon, (France) in 2019 and at the Integrative Neuroscience and Cognition Center (CNRS UMR 8002 - Université Paris Descartes), Paris, France in 2021.
