At the same time she criticises the so-called ‘de-development’: the anti-technological attitude of thirty-year olds regarding inventions such as E numbers, genetic technology and vaccinations.Next to her activities as a writer and columnist, Rosanne is often to be found in the laboratory to research the bacterial metabolism in the flora of the human body. She is in favor of open science and citizen science and she enjoys speaking about the role of science, technology and innovation in our daily lives.
