Research Interests
The domain of specialization is the epidemiology and evolution of antibiotic-resistant bacterial populations, with special emphasis on the factors involved in the selection, dissemination and evolution of resistance genes, and especifically in the characterization of bacterial ecotypes and mobile genetic elements (plasmids, transposons and integrons). Current research interests include the characterization of the virulence profile and biofilm-producing ability of particular Escherichia coli pathotypes, and the development of scientific and technical skills in high-throughput approaches applied to the epidemiological typing, detection and characterization of particular antibiotic resistant clonal complexes.
