Introduction
I was a post-doctoral researcher in the FMRIB plasticity group at the University of Oxford. My main research focus is the interaction among several healthy and modifiable lifestyles with children's brain activity and structure, cognition, and academic achievement. Specifically, my interest is to contribute to the geographical gap in this research area and to study to what extent healthy lifestyles could be associated with a shortening of the socioeconomic and school vulnerability gap.
