On 14th of October 2022, the Ruisdael community gathered at the Green Village of the TU Delft campus for the annual Ruisdael Science Day. This annual gathering marks the day of the year when scientists who work within the framework of the Ruisdael project or in a related field come together and share their work with each other. More than 60 scientists, PhD students and post-docs of the affiliated institutes attended this year’s Ruisdael Science Day. During this edition of the Science Day, the program was divided into a total of six themes. The whole program can be seen below together with the links to the presentations or posters. For some topics, there is no link provided since the content is not made publicly available yet.
