Jan-Erik Berdal

Jan-Erik Berdal is an Associate Professor at the Faculty of Medicine, University of Oslo, affiliated with the Department of Microbiology and Infectious Diseases. His research focuses on infectious disease epidemiology, antibiotic resistance, and critical care microbiology, with extensive contributions to understanding hospital-acquired infections, sepsis, and SARS-CoV-2 dynamics. He collaborates with Akershus University Hospital and participates in multinational studies like ISARIC-COVID-19.

Research interests include:

• Microbial pathogenesis in critical care settings
• Antibiotic therapy and resistance patterns
• Viral infections and immune responses (notably SARS-CoV-2)
• Development of diagnostic tools for infections

Recent publications highlight his work on fecal microbiota transplantation for C. difficile, longitudinal transcriptomics in COVID-19, and biomarker utility in predicting outcomes. Studies span clinical trials, cohort analyses, and computational biology tools.

Key collaborations include institutions across Norway and international networks (e.g., ISARIC). His work bridges clinical microbiology, public health, and data-driven diagnostics, emphasizing real-world applications in hospital settings.
