Fernanda Peralta was born and lives in São Paulo. She studied Architecture and Urbanism at USP and has been working as a visual artist and sculptor since 2017. Everyday life and the ordinary are frequent sources of inspiration for her to create and draw: she draws what she sees in front of her, but also what she encounters in the world of dreams. In her work, she uses gouache and acrylic paints on canvas and paper, oil pastel sticks, and colored pencils. In addition to exhibiting her work, she has illustrated for publishers and magazines such as Editora Martins Fontes, Revista Jacobin, Editora Biruta, and The Architectural Review.
