I am a Professor at the Faculty of Pharmacy, Federal University of Rio Grande do Sul (UFRGS), Brazil, where I work in Toxicology and Toxicological Analysis. I hold a PhD in Pharmaceutical Sciences - Toxicology from the University of Porto, Portugal, and I have experience in in vitro and in vivo toxicological evaluation. My research interests include the mechanisms of xenobiotic-induced toxicity, with particular emphasis on neurotoxicity, hepatotoxicity, cardiotoxicity, pesticides, drugs of abuse, and emerging psychoactive substances. My work integrates biochemical, cellular, molecular, and analytical approaches to investigate toxicological mechanisms and identify biomarkers of toxicity. My research is driven by the goal of advancing mechanistic toxicology and generating evidence that contributes to chemical safety assessment and the protection of human health and the environment.
