My research has been performed at the Department of Biochemistry at the University of Oviedo, Darmstadt Technical School, Germany and the Department of Genetics, University of Osnabrück, Germany. For a long time, I focused on the study of different signaling pathways in the yeasts Saccharomyces cerevisiae and Kluyveromyces lactis. These pathways are highly conserved throughout evolution; therefore, studies in yeast can serve as a model for humans. Therefore, I have extensive experience in regulation studies that involved the analysis of promoters, transcription factors and protein kinases, for which it was necessary to obtain mutants and perform their functional analysis. More recently, I have participated in transcriptomic studies for the identification of the targets of one of the transcription factors of the cell wall integrity pathway in K. lactis. Starting in 2007, I started collaborating in the line of research on "Pathogenic Bacteria of Clinical and Agrifood Interest" of the University of Oviedo, in particular, in the study of the pathogenic bacterium Salmonella enterica. I am interested in epidemiological surveillance and in the molecular bases of resistance and virulence, using traditional techniques and genomics.
