Dr. Jerusa Maria de Oliveira is a researcher in nanobiotechnology and toxicology, holding a Ph.D. in Cell and Structural Biology from the Federal University of Viçosa, with advanced postdoctoral training spanning biotechnology, ecotoxicology, and nanotoxicology at UFAL, INCT AmbTropic, and currently as a CNPq DCR fellow at the Federal University of Goiás. Her research operates at the interface of nanomaterials science, redox biology, and translational toxicology, focusing on biocompatible nanostructures, oxidative stress mechanisms, and predictive alternative platforms aligned with the One Health paradigm. Dr. Oliveira has established a consistent track record of high-impact scientific contributions, including publications in leading international journals as well as patented technologies. Her work is distinguished by integrating mechanistic toxicology with innovative bioassays using alternative models and wildlife systems, enabling scalable, ethical, and high-resolution assessment of environmental and biological risk. She is the founder of NexusBioTox, a biotechnology initiative dedicated to advancing alternative toxicological frameworks and reducing reliance on mammalian models, bridging academic research and technological innovation. Furthermore, she actively contributes to the scientific community as a reviewer and guest editor for international journals, reinforcing her leadership in nanotoxicology and sustainable biotechnology.
