Microbiology, Infection and Infection Control
Our interdisciplinary group conducts research in a range of infection-related fields, including antimicrobial stewardship and infection control in hospitals, clinical infections, antimicrobial resistance, microbiological diagnostics – including molecular epidemiology and next-generation sequencing – as well as human papillomavirus (HPV).
Research Areas
- Antibiotic use and antimicrobial stewardship in hospitals
- Antimicrobial resistance (AMR): laboratory diagnostics, epidemiology, and mathematical modelling
- Hepatitis B and C, health complications among people who use drugs
- Human papillomavirus (HPV) – National Reference Laboratory
- Infection surveillance and control in hospitals
- Clinical translational research: collaboration between microbiology laboratories and clinical departments on infection-related topics
- Laboratory diagnostics
- Molecular epidemiology of infectious diseases, precision medicine
- Next-generation sequencing, metagenomics, nanopore sequencing
