  As a doctoral candidate at University of Salamanca, García conducted research on cancer medicine as a university research assistant for the Spanish National Research Council. She earned a doctorate cum laude in the nuclear biology of cancer and translational medicine in the university's Cancer Research Centre [es] in 2018, advised by Atanasio Pandiella Alonso.
