Christian G. Giske

Christian G. Giske is a Professor of Clinical Bacteriology at Karolinska Institutet, part of the Department of Laboratory Medicine. He also serves as a Senior Physician at Karolinska University Hospital. His research focuses on antimicrobial resistance (AMR) in pathogens such as Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa, with translational studies on bacteriophage therapy and microbiome interactions. Dr. Giske completed his medical training at the Norwegian University of Science and Technology (2000), earned his PhD at Karolinset (2007), and became a Professor in 2018.

Education:

• MD: Norwegian University of Science and Technology, 2000
• PhD: Karolinska Institutet, 2007
• Specialist in Clinical Microbiology, 2007
• Associate Professor, 2010

Research Interests: His work spans AMR mechanisms, clonal spread of resistant strains, and therapeutic innovations like phage therapy. Key themes include:

• Epidemiology of drug-resistant Gram-negative bacilli
• Microbiome impacts of antibiotics
• Bacteriophage-based treatments

Grants & Collaborations: Active in multiple projects funded by the Swedish Research Council and international bodies, including studies on phage-antimicrobial combinations, Pseudomonas infections in cystic fibrosis, and global AMR surveillance. He leads a research group with 15+ affiliated members.

Labs/Teams: Directs the Antimicrobial Resistance research group at Karolinska, collaborating internationally on projects like the PILGRIM EU initiative studying AMR in gut microbiota.
