Dr. Maretti-Garcia earned her B.S. degree in biomedical sciences, M.S. in Parasitology, and Ph.D. in Molecular and Cellular Biology in Brazil. After completing her postdoctoral training at the University of California, Los Angeles (UCLA), where she studied the immunopathology of tropical diseases, she joined the University of Southern California (USC) to study liver diseases.

Recently, Dr. Maretti-Garcia became an Assistant Professor at Keck School of Medicine of USC, and her research interest mainly concentrates on the contribution of the immune response to the progression of chronic liver diseases. She is an expert in cutting-edge technologies used for transcriptomic analyses and for real-time cellular behavior assays.
