Research Interest

  1. Comparison of phenotypes/genotypes of bacterial species/strains from different niches, clinical origins and hosts
  2. Analysis of the genomic structure and potential for horizontal gene transfer of phages (bacterial virus) and of other mobile genetic element
  3. Study of antimicrobial resistance patterns and mechanisms of resistance
  4. Investigation of the biological activity of new materials and new biocompounds against various pathogens
  5. Investigation of tailor- made strategies for infection control and risk assessment for bacterial colonization and infection.
