Professor David Walker

David Walker is an architect, designer, and specialist in innovation and new product development. Most of his professional work has been in the realm of building bridges between two tribes – managers and designers. While a fair proportion of his work has been as a professional consultant and writer on design and innovation, he is convinced of the prime importance of visual thinking and visual communication. Verbal analysis of design can only set up frameworks; real quality and know how is embedded in visually led processes.

Mark Dowling FRSA, AIEMA

Mark was BT’s compliance manager with 21 years relevant experience; he was responsible for implementing the WEEE, RoHS, Biocidal, Batteries and EuP Directives and has a very good appreciation of the broader environmental, business, consumer and social policy
context that affects producers. For eight years Mark was BT’s plastics mouldings manager, a role that also incorporated environmental lifecycle management. Mark is familiar with the practical implementation of recycled materials, colour matching of polymers, physical test methods including tensile and falling weight impact testing. He also set BT’s quality standards for mouldings and colour matching and for bespoke test methods such as resistance to graffiti removers. He was responsible for phasing out various heavy metals and flame retardants in polymers 10 years ahead of the current RoHS (Restriction in the use of Hazardous Substances) legislation.

Claire Carter BSc (Hons) MSc

I have recently joined Giraffe after completing an environmental science MSc this was to change direction following many years in the actuarial pensions sector. My MSc thesis looked at comparing the global warming potential of different types of egg packaging which was met with much amusement by my fellow students since I was pregnant while writing it! Since joining Giraffe I am able to use the life cycle analysis skills acquired during my MSc to assess environmental impacts of all kinds of materials and products. Outside Giraffe my habits and “green” credentials have been tested with the arrival of my daughter and yes I do use washable nappies – but I am looking forward to the day she is potty trained!
