Prof. dr. John W. A. Rossen has a 30-year history in Molecular Virology and Microbiology and published over 220 peer-reviewed articles (H-index 47). He obtained a Bachelor of Science in Mathematics & Physics (1989, Faculty of Mathematics and Science, Utrecht University) and a Master of Science in Biology (1991, Faculty of Biology, Utrecht University). In 1996, he obtained a PhD in (Molecular) Virology and Cell Biology at the Faculty of Veterinary Medicine, Utrecht University. His PhD research focused on “Coronavirus – Host Interactions.” Since 2004, next to his (fundamental) research, he has been actively involved in Molecular Diagnostics and the Prevention of Infectious Diseases. As a Professor for Personalized Microbiology, he successfully implemented Next-Generation Sequencing for routine Clinical Microbiology and Infection Prevention. He is affiliated with the Department for Medical Microbiology and Infection Prevention at the University Medical Center Groningen. His research group focuses on applying metagenomics and metatranscriptomics to Clinical Microbiology and Public Health. He is the immediate past president of the ESCMID Study Group for Genomic and Molecular Diagnostics (ESGMD) and the current treasurer of the Royal Netherlands Society for Microbiology. In 2020, he took a 2-year sabbatical and worked at a US start-up company (IDbyDNA) to further power science and medicine to improve health by decoding the unknown, including setting the standard for identifying and understanding microorganisms and their role in human disease. From March 2020, he is affiliated as an Adjunct Professor with the Department of Pathology of the University of Utah School of Medicine. In October 2021, he started as a medical molecular microbiologist at the Laboratory for Medical Microbiology and Infectious Diseases (LMMI) at the Isala Hospital.Prof. dr. John W. A.
