Opening Utrecht Science Week with keynote by Juliette Legler on the hidden influence of environmental chemicals
On Friday 25 September, the annual Utrecht Science Week will kick off at Utrecht Science Park. The official opening will feature the Utrecht Science Lecture, which this year will be delivered by Prof. Dr. Ir. Juliette Legler. Legler is Professor of Toxicology at Utrecht University, affiliated with the Faculty of Veterinary Medicine, and heads the One Health Toxicology research group at the Institute for Risk Assessment Sciences (IRAS).
Influence of environmental chemicals
In her lecture, Healthy Planet, Healthy People: Towards Solutions for a Polluted World, she takes the audience into the world of environmental chemicals. Juliette Legler and her team research how environmental pollutants like endocrine-disrupting chemicals and microplastics affect the health of humans, animals, and ecosystems. Environmental chemicals are all around us: in products we use every day, in food packaging and in the environment. Increasingly scientific research indicates that some of these substances can disrupt the hormone system. What does that mean for the health of people and animals? And how can science, policy and society contribute to a healthier living environment?
By promoting connection across disciplines and sectors, her research has moved from diagnosing the problems towards working on solutions for a healthier future. These solutions include innovative chemical risk assessment approaches and the development of safer chemicals and materials.
During her keynote, Juliette Legler shares the latest insights from the research and discusses the challenges and opportunities that this knowledge offers. Her story underlines the importance of science that not only produces new knowledge, but also contributes to solutions for urgent social issues.

Over a week full of science and innovation From 26 September to 5 October, a unique glimpse behind the scenes at Utrecht Science Park From Friday 26 September to Sunday 5 October, Utrecht Science Park will be transformed into an open house for (applied) science and innovation for everyone. The Netherlands' largest science park, where 31,000 employees and 55,000 students work every day to create a healthy, sustainable society, will offer a rich programme of engaging lectures, interactive workshops, guided tours and high-profile interviews during that week. Visitors can now register (free of charge) for the various programme components. Opening by Prof. Dr. Jan van de WinkelUtrecht Science Week kicks off with a special lecture by Prof. Dr. Jan van de Winkel, founder and CEO of Genmab, an international biotechnology company specialising in antibody therapies for the treatment of cancer and other serious diseases. During this Utrecht Science Lecture on Friday 26 September, he will explore how immunotherapy is revolutionising medicine.Varied programme for various target groupsAfter the weekend, we look forward to a highly varied programme for diverse target groups. There will be lectures, workshops and guided tours for those interested in science and innovation, policymakers, healthcare and sustainability professionals, and families with children.The week offers a unique opportunity to see where and how the science of the future is being shaped. Visitors will have access to normally closed facilities such as the high-tech plant lab NPEC, can take part in guided tours at Utrechtinc and join an expedition to Amelisweerd. In addition, you can be inspired during the Sustainability Day organised by Utrecht University of Applied Sciences and Utrecht University and contribute your ideas about AI in healthcare at UMC Utrecht. Of course, there are also various events for students, such as the Utrecht Science Week Pub Quiz and the final of the Sustainable City Challenge, where students pitch their ideas for making various neighbourhoods in Utrecht more sustainable. We will conclude Utrecht Science Week on Sunday 5 October with an event for younger visitors, as it is Science Weekend. During this national science weekend, visitors can learn about the world of research, technology and innovation in an accessible and interactive way. From conducting experiments in a real laboratory to building robots themselves or discovering how paediatricians and researchers work together on groundbreaking treatments. This year, visitors will get a unique behind-the-scenes look at Utrecht University of Applied Sciences, Utrecht University, the Wilhelmina Children's Hospital (WKZ) and the Princess Máxima Centre, among others. Full programmeBut there is much more to experience during Utrecht Science Week. Visitors can view the full programme and register here. Except for the Betweterfestival, all events are free of charge, but some have limited capacity, so it is recommended to register soon.
USP still largest science park in the Netherlands
Growing Utrecht Science Park still largest science park in the NetherlandsCampuses and science parks of the Netherlands are essential for employment growth and new business activity. Innovations and innovative collaborations result in solutions that accelerate social transitions. So says the research report published on December 4 by Buck Consultants International (BCI). The report shows that the Utrecht Science Park has also grown strongly in terms of employees and, with more than 31,000 employees, remains by far the largest science park in the Netherlands.
