Oscar Salvador Barrera Vázquez received his BSc in Pharmaceutical Biological Chemistry from the Universidad Autónoma Metropolitana–Xochimilco and his MSc and PhD in Molecular Infectomics and Pathogenesis from CINVESTAV–IPN. He subsequently completed postdoctoral training in phytopharmacology at the Faculty of Medicine, Universidad Nacional Autónoma de México (UNAM), where he currently serves as a Full-Time Associate Academic Technician in the Department of Pharmacology and as a postgraduate tutor in Biological Sciences. His research focuses on natural-product drug discovery using chemoinformatics, network pharmacology, molecular modeling, and experimental pharmacology to identify new bioactive molecules for the treatment of chronic venous insufficiency, aging-related diseases, cardiovascular disorders, and viral infections. His interests also include medicinal plants, phytochemistry, in silico toxicology, and the preclinical evaluation of efficacy and safety.
