María Soledad Ramírez

María Soledad Ramírez is a Professor at California State University, Fullerton, specializing in molecular mechanisms of antibiotic resistance and bacterial pathogenesis. She holds a PhD and MSc in Biological Sciences from the University of Buenos Aires, Argentina. Her research focuses on understanding the dissemination and evolution of antibiotic resistance in clinical isolates, particularly in Acinetobacter baumannii, Klebsiella pneumoniae, and other Gram-negative pathogens. Key areas include integron-mediated resistance, genetic determinants of multidrug resistance, and the epidemiology of resistant strains.

Her work combines genomic analysis, molecular biology, and clinical microbiology to address global antibiotic resistance challenges. Representative studies include investigations into carbapenemase-resistant Klebsiella pneumoniae, the emergence of indigo-pigmented Acinetobacter baumannii lineages, and the role of zinc ionophores in reversing aminoglycoside resistance. Publications span high-impact journals like Antimicrobial Agents and Chemotherapy, J. Clinical Microbiology, and Genome Announcements.

Dr. Ramírez’s research also explores novel diagnostic methods, such as MALDI-TOF mass spectrometry for rapid pathogen identification. Her lab (https://msramirezlab.weebly.com) focuses on translational research bridging fundamental discoveries and clinical applications. Despite no explicitly listed awards or grants, her extensive publication record reflects sustained contributions to microbiology and antimicrobial resistance studies.
