Sandra Maria Basílio Quinteira is an Assistant Professor/Principal Adjunct Professor at the Advanced Polytechnic and University Cooperative—CESPU (IUCS/IPSN) and an invited Assistant Professor of Microbiology/Food Microbiology in the Faculty of Sciences at the University of Porto. She has more than 20 years of experience teaching several topics in microbiology, epidemiology, and public health. She holds a Ph.D. in microbiology, and she is an integrated researcher at BIOPOLIS/CIBIO-InBIO (Research Centre in Biodiversity and Genetic Resources, Associate Laboratory) and a collaborator–researcher at TOXRUN-IUCS. She has been working for the last 20 years in the field of the epidemiology of antibiotic resistance, developing resistance surveillance studies from several ecological niches within the One Health context but also researching the molecular characterization of genes/genetic elements associated with the horizontal dissemination of antibiotic resistance and typing. Antimicrobial resistance within poorly studied remote habitats, characterization of the antimicrobial activity of fish mucus against human pathogens, and Planctomycetota antibiotic-resistant mechanism elucidation currently constitute her main research focuses. Food safety is also a present-day area of interest to her.
