I have been working with Á. del Río at the University of Murcia, Spain, supported by a MarieCurie Individual Fellowship between May 2016 and October 2017. Now I am on a FWO PostDoc at the Free University of Brussels, Belgium, in the working group of Eric Jespers. This page is being maintained once in a while. It was last updated on November 20th, 2017.
