Raquel Portela is a Researcher at the Molecular Microbiology of Bacterial Pathogens Lab hosted at Unidade de Ciências Biomoleculares Aplicadas (UCIBIO/FCT- NOVA). Raquel performed her MSc in the epidemiology of nosocomial enterococci and finished her PhD in Molecular Biology at NOVA School of Science and Technologies, (FCT-NOVA), in 2019, with the thesis entitled: "New studies in the resistance to beta-lactams and in cell wall damage survival in Staphylococcus aureus: an integrated approach." Her main scientific interests are in the field of Bacterial Pathogenesis and Molecular Bacteriology namely: antimicrobial resistance mechanisms, peptidoglycan biosynthesis, stringent response, transcription regulation, genetic competence and bacterial rheology. Between May 2021 and September 2022 Raquel performed a Post-Doc at the Microbial Stress Lab where she worked with ROS detoxification by peroxidases in E. coli and metal tolerance in S. aureus. Raquel has authored 9 peer-reviewed journal articles and 7 conference proceedings among which 13 as first-author and as a total of 242 citations; Raquel has participated in 9 national and international research projects and supervised more than 10 undergraduate and 3 master students. Her work was presented in 10 oral presentations in conferences and seminars and in 29 communications in panel in National and International conferences. She is an ad-hoc reviewer for PeerJ and PLOS ONE, has participated in master thesis and undergraduated examinations and was a reviewer of international grants. Raquel was recently awarded with a Research Grant from the European Society of Clinical Microbiology and Infectious Diseases. ESCMID Research Grant 2022.
