Dr. Sher Ali is a researcher at the University of São Paulo (USP), Brazil. He holds a Ph.D. in Chemistry from the Federal University of Paraná (UFPR), Brazil, where he applied high-resolution magic-angle spinning nuclear magnetic resonance (HR-MAS NMR) spectroscopy in metabolomics and natural products chemistry. His current research focuses on mass spectrometry (MS)-based analysis of food and biological samples to assess exposure to multiple mycotoxins, environmental contaminants, and associated biomarkers. His multidisciplinary research encompasses mycotoxicology, exposure and risk assessment, toxicology, and food chemistry. He has authored numerous research articles in peer-reviewed scientific journals. His broader research interests include integrating advanced MS and NMR techniques with multi-omics approaches to advance analytical and environmental health research.
