Dr. Barros' training includes doctoral training with Dr. Rondinelli Herculano at the Sao Paulo State University in Brazil, where I developed a biomaterial-based wound dressing to treat chronic wounds such as diabetic foot wounds and postdoctoral training with Dr. Ali Khademhosseini and Dr. Han-Jun Kim at the Terasaki Institute for Biomedical Innovation where I developed an interpenetrating ion-covalent crosslinkable bioink for 3D bioprinting of tumor in vitro models. In 2019, I held a FAPESP Visiting Researcher scholarship at the University of California Los Angeles (UCLA) and worked with Dr. Junmin Lee and Dr. Ali Khademhosseini to develop a 3D bioprinted full-thickness skin-on-a-chip model.
