Research

Research interests

Co-infections caused by Candida albicans and Staphylococcus aureus result in worse disease compared to mono-infections due to the synergistic interaction between C. albicans and S. aureus. Seána’s fellowship aims to define drivers of this synergy with a view to mitigation. She interrogates fungal-bacterial-human cell cultures with omics coupled with phenotypic and infection assays. 

Research projects

  • Fungal - Bacterial Biofilms
  • Co-infection Biology
  • Candida albicans - Staphylococcus aureus interactions
  • Candida parapsilosis - Staphylococcus aureus interactions 
  • Social Justice of Infections
