Biography Jan Thomas Rosnes

I have been employed by Nofima since 1993 and have worked with different issues related to the impact of microorganisms on foods. The research areas have included control of the growth and survival of pathogenic microorganisms, but I also work with microorganisms that reduce quality. When the industry uses different types of technology to preserve or extend its shelf life, I participate in risk assessments to ensure food safety. A main area has been heat-treated foods and the challenge here is heat-tolerant spore-forming bacteria. I graduated from the University of Bergen in the field of oil microbiology. During the last 10 years I have been teaching at various colleges and in recent years I have been in charge for the topic “food microbiology” at the University of Stavanger.
