She received her PhD in the history of art and visual arts from the same university and participated in a year-long collaborative study program at the Université Sorbonne Nouvelle–Paris 3. Her doctoral thesis, “Word in Brazilian Art: Mira Schendel and Waltercio Caldas,” focused on the relationship between text and image in Brazilian contemporary art, especially in the work of those two artists. Her research also considers the connections between art and poetry in Brazil, concrete and neoconcrete art, and the production of artists’ books. Mannarino participated in the CAA-Getty International Program in 2015.
