Julia studied pharmacy at the Complutense University of Madrid. As an undergrad, she worked on the Anisakis simplex antigens with Prof. Carmen Cuéllar. She earned her Ph.D. in 2021 at the same university, with Prof. María Molina and Prof. Victor J. Cid, researching human diseases by reconstructing signaling modules in S. cerevisiae. Besides, she went on two scientific stays: in Prof. Jonathan C. Kagan’s lab (Harvard University), learning about antiviral innate immunity, and in Prof. Suzana Salcedo’s lab (CNRS-Lyon), investigating Brucella‘s host-pathogen interactions. In April 2021, she joined the lab to study the roles of Cdc42 effectors in promoting the irreversibility of the cell-cell fusion process.
