Mona Johannessen


Professor

Job description

Mona Johannessen (PhD) is the leader of Research Group for Host-Microbe interaction (HMI), at Department of Medical Biology (IMB). 

She is professor in molecular/cell biology and is especially interested in molecular aspects of host-microbe interplay, including bacterial adaptation to host which includes, but are not limited too, the expression and functions of factors involved in adhesion, invasion and immune evasion. 

Johannessen is also highly involved in teaching at bachelor-, master- and PhD level courses, and in mentoring of post docs as well as supervision of PhD-, master- and bachelor students.

    Research interests

    Johannessen main research interest is to identify, explore and get in-depth understanding of species such as Staphylococcus aureus, Enterococcus faecium and/or Klebsiella pneumoniae with respect to...

    1) host-microbe interaction, especially bacterial factors involved in colonisation and infection.  

    2) bacterial adaptation to various host niches and phenotypic heterogeneity 

    3) bacterial membrane vesicles

     

    Teaching

    Johannessen is in charge of MBI-1002 Molecular and cell biology (15 ECTS), a course taken by seven different study programs.

    Additionally, she currently teach in MBI-3012 Advanced methods in experimental biomedicine (30ECTS), MBI-3014 Infection, inflammation and immunity (10 ECTS), MBI-8005 advanced and interactive antimicrobial resistance course (3 ECTS) at UiT and at the PhD course "Pathogen immune vasion strategies" at NTNU. 

    She has previously been in charge of Study program for Biomedicine, been course leader for Msc-courses named "Virology", "Mammalian cell culture", "Infection, inflammation and immunity", and taught in Bsc-courses named "Biochemistry", "Cell biology", "Genetics" and Msc-courses named "Eukaryotic transcription factors", "Normal flora/Infection/Immunity", "Health-security-environment", "Molecular genetical methods", and PhD courses "Frontiers in molecular and structureal biology".
