Research interests
Prof. Dr. John W.A. Rossen is Endowed Professor
of Medical Microbiology and Infection Control at the University of
Groningen and Isala Hospital (Zwolle, NL), and Medical Head of
Innovation & Science at Isala Hospital. With 30+ years of
experience in molecular biology, virology, and microbiology, he has
authored 235+ peer-reviewed publications and is internationally
recognized for bridging science, healthcare, and innovation.
He holds a BSc in Mathematics & Physics, an MSc in Biology, and
a PhD in Molecular Virology and Cell Biology (Utrecht University,
1996, coronavirus–host interactions). His career includes
leadership roles such as Chair of scientific study groups, Faculty
Council Member, Director of R&D and Head of Microbiology &
Product Strategy at IDbyDNA (USA), and Scientific Lead of the
€7M Horizon Europe project DRAIGON (draigon.eu). He also
serves as Adjunct Professor at the University of Utah School of
Medicine.
John has supervised 24 PhD students and actively contributes to
training and international collaboration through the Concilium
Medical Molecular Microbiology and the NVMM Working Group for
International Medical Microbiology.
His research group, Antimicrobial Resistance, Genomics, and
Epidemiology (AGE), applies a One Health approach to understand the
dynamics of antimicrobial resistance (AMR) and emerging pathogens
across human, animal, and environmental domains. By combining
advanced molecular tools with artificial intelligence and machine
learning, AGE uncovers resistance and virulence mechanisms,
pathogen transmission pathways, and develops predictive models of
resistance emergence, disease outcomes, and outbreak potential.
This work directly contributes to improved antimicrobial
stewardship, infection prevention, and evidence-based public health
policy.
