About me

  • My field of expertise is bacterial physiology and I am a recognized expert in
    the biology of bacteria of the genus Shewanella. My research lines focus 

  • on three inter-related areas:
    1-Respiration-induced biofilm formation (RIBF).
    2-Genomics of Shewanella spp.
    3-Antibiotic resistance from a One-Health perspective.

    Grants after PhD completion:

  • Biofilm physiology: Respiration-induced biofilm formation (RIBF)
    My research focuses on the association between respiration phenomena and
    bacterial colonization of biotic and abiotic substrata through biofilm
    formation. I try to unravel the physiological and signalling mechanisms
    linking these two prima facie unrelated processes.
    In the marine indigenous bacterium and emerging pathogen /Shewanella algae/,
    my research has shown a strain-specific association between respiration of
    alternative electron acceptors and biofilm formation, and I have demonstrated
    that it is the anaerobic reduction of these compounds that triggers
    downstream events leading to surface colonization. Our efforts are now
    focused on understanding the molecular mechanisms regulating this response,
    with a special focus on taxis and c-di-GMP signaling.
    I have expanded this respiration-biofilm tandem interplay to other bacterial
    models (uropathogenic Escherichia coli), where I have been able to find 

  • associations with implications in infectivity. I currently explore the
    role of respiratory nitrate utilization in biofilm-related processes in
    other E. coli pathotypes. 

  • Genomics
    New times bring new technologies, and whole genome sequencing has
    revolutionized many ‘gold standards’ in classic microbiology. I am
    interested in gaining a deeper understanding on S. algae/Shewanella spp. diversity and 

  • evolution through genome sequence analysis to correlate genomic composition
    with phenotypic diversity and niche occupation. While doing so, we are also making 

  • efforts to shed light on the taxonomy of Shewanella spp. We plan to apply similar approaches to gain a better understanding on the colonization of organ niches by distinct strains of human-associated microorganisms. 

  • Antibiotic resistance
    Antibiotic resistance is a global threat, perhaps one of the most important
    challenges for humankind in the coming decades. I am interested in the
    environmental dimension of this phenomenon and the transmission of antibiotic
    resistance determinants from environmental to pathogenic bacteria. I
    currently lead projects that interrogate host specificity of mobile elements
    in Shewanella spp. and Vibrio spp. in aquatic environments, both in the 

  • water column and in sediments. Efforts are also devoted to determining levels
    of antibiotic residues and relating them to the presence and transmission of
    mobile genetic elements including antibiotic resistance determinants.


  • -Supervision of diverse BSc and MSc theses in Sweden and abroad.
    -Co-supervision of 2 PhD candidates (ongoing).

  • 200 h of teaching (Microbiology) at different levels (BSc, MSc, PhD courses,
    laboratory courses, etc.), including opponent in B. Sc. and M. Sc. programs
    in Sweden and abroad.
    -8 weeks of pedagogical training in Sweden.
    -Accredited competence as Senior Lecturer (Assoc. Prof.) by the National
    Agency for Quality Assessment and Accreditation of Spain (approximately
    equivalent to Docentur).
