CERN Accelerating science


Our Team & our Community

IdeaSquare is proud to foster a community of mentors and supporters from CERN and the larger community around high energy physics and the Sustainable Development Goals.

Through our interlinked activities — hosting R&D&I projects, supporting selected EU-funded projects, prototyping, running design thinking workshops and educational programmes, organising events and sharing experimental knowledge activities — previous participants have the opportunity to continue contributing to our extensive network of tech-savvy experts. These members of our community give talks to our students, show them around the experiments they are working on, mentor participants in their projects, create videos for their benefit, and most importantly volunteer their time even for a free form chat. Our students value these interactions that make their visits so much more diverse. If you are curious about these activities and would like to join us, please don’t hesitate to contact the team!

IdeaSquare is made up of a community of gifted scientists, engineers and collaborators who guarantee cutting-edge outputs. Besides the core team’s friendly faces below, you will find our mentors, partners and many more collaborators on the corresponding pages, as well as featured in our blogs. All of them are eager to share, experiment and innovate. Don’t hesitate to reach out to us if you have questions for any of us!

    Alexia Yiannouli

    Alexia graduated as a veterinary surgeon from the University of Surrey, before going on to study for a Master’s in Science Communication at Imperial College London. During her studies, Alexia gained journalism experience writing for veterinary publications such as Vet Record, and worked as editor of a veterinary news site. She co-edited Surrey vet school’s first newsletter, and was co-editor of Imperial College London’s science magazine, I, Science. Alexia joined CERN in August 2021, first as an intern working on the Sparks! Forum and with the Arts at CERN programme, before working as Junior Communications Officer of CERN openlab, and now Science Communication Officer in IdeaSquare. In her free time, Alexia still writes monthly articles for a veterinary magazine, and can be found doing anything creative - from bullet journalling to embroidery.

    Dina Zimmermann

    Dina finished her Master’s degree in Structural Engineering from the Norwegian University of Science and Technology in 2022. After taking a Design Thinking-course during her studies, her focus shifted away from Civil Engineering and over to Mechanical Engineering. The last summer of her studies, she got an internship as a Product Developer at Laerdal Medical. In collaboration with the Department of Mechanical and Industrial Engineering she wrote her thesis on the development of a motor speed control system for a propulsion-assisted sit-ski. After graduation, she joined IdeaSquare as the Prototyping Expert.
