Madeleine's background is in illustration, graphic and product design. She set up her design practice Mibo in 2001, collaborating with major brands on homewares and stationery products. In 2011, in a bid to create a sustainable product for children, she released her award winning make-them-yourself paper animals. Madeleine then went on to adapt the animal characters for a successful series of books for very young children, introducing the wild animals and their natural habitats, which have now been translated into many languages. Alongside this work, she provides graphic design and illustration services for like-minded organizations.

Madeleine is current re-aligning her practice to help to explore how design can help address our current social and environmental challenges. She recently took time to explore this further, graduating from The University of Brighton with an MA in Sustainable Design (Dist) in 2019 and also studying Design for Social Innovation at Kingston University.
