Duncan is a co-founder and director at Vitamins, a Design and Invention Studio based in Spitalfields, London.

He trained as a Mechanical Engineer and Designer at the University of Bath, Royal College of Art and Imperial College, London, and often draws from his past work in the department of Cognitive Ergonomics at Renault automotive. As well as consulting internationally for large firms such as Blackberry, Olympus and Samsung, Vitamins also develop their own designs, some of which are patented, and one of which is licensed.

Duncan set up Vitamins with two fellow graduates of the Royal College of Art in 2009. Duncan was the James Dyson Innovation Fellow in 2010 and his work has seen him as a finalist in the Saatchi & Saatchi World Changing Ideas Award as well as being selected as one of Wallpaper* magazines 10 Designs for 2010.

Duncan is the creator of the Morph Wheel foldable wheelchair wheel, a patented product that is currently on sale and which has this year won the Design Museum’s Design of the Year in the Transport category.
