Global Sciencejournalist

Bio / Specialization

Marianne Heselman's goal is providing news on biotechnology and environmental and food sciences. Her curiosity about how life works is sparked by reading about the results of research in these fields. She likes the challenge of ordering information from different sources to craft clear and accessible stories.
She is also interested in social processes. Science is never politically neutral. Results - together with a PR-story can profoundly influence careers and the market value of companies. She therefore situates scientific results within a political context in my writing.
Marianne Heselman's stories, essays, start documents and reports are guided by the quality of the evidence and the arguments put forward, rather than commercial stakes or opinions.
She is specialized in writing news articles, features and trend articles for newspapers and journals. In addition, she has many years experience as an editor and trainer in courses Sciencejournalism and Science communication at the Aplied University of Utrecht.
In 2010, Marianne Heselmans has set up DePerskamer, together with sciencejournalist Astrid Smit. They provide courses in science communication on universities; in 2011, she has set up ImpactReporters for communication in the field of water, food and energy, together with journalists Hans van de Veen and Han van der Wiel.
