Frank Schuren received his PhD at Groningen University in 1987 on the molecular biological analysis of fungal development. After a postdoc in Groningen and at the ETH Zurich in Switzerland he joined TNO in 1996. At TNO he started the implementation of microarray technology in applied research which led to successful implementation in applied microbial research. These include novel diagnostic tools such as the Legionella chip and the analysis of complex microbial populations (such as the intestinal and vaginal microbiota). Furthermore Frank has extensive experience with different approaches for novel antimicrobial strategies. Currently Frank is senior scientist in the Microbiology team within TNO and actively involved in activities towards better understanding the role of the microbiome in human health and especially in innovative ways to modulate gut microbiome in order to improve human health, with a specific focus on dietary fibers and innovative approaches for dealing with individual variation as well as microbiome driven drug metabolism.
