Ellis Bartholomeus started her career as a industrial designer at the Design Academy in Eindhoven. Via signage design, graphic, web and interaction design she became a game designer and created serious games for ten years with Laika.nl. Gaming appeared to be the ultimate medium for clients to get a message to their clients/users, for educational and health purposes, to help users/players develop knowledge, skills or attitude on different topics. In 2010 she became eager to get more in-depth involved with the theory behind play and gaming as a medium and tool and not just for fun. Gaming has great potential in education, health and daily social life. Ellis is consulting in several game design projects and plays the role as the ambassador of the player to protect ad facilitate their experience and journey. She shares knowledge and experience on game design via hands-on workshops to game professionals and no game professionals and teaches interaction design and design thinking at universities. As game researcher and game consultant she is full-time in Wonderland and learning and talking about the value of play and intrinsic motivation.
