A design engineer from the University of Bath was invited to Downing Street to celebrate his contribution to the NHS.

Simon Halsey is one of 100 people recognised in a new book Extraordinary You - Science in Healthcare, which looks at the work of scientists within the NHS and details their reasons for choosing the career.

The book was showcased at a reception at 11 Downing Street which was attended by health minister Ann Keen, and chief scientific officer Professor Sue Hill.

Mr Halsey works for the Bath Institute for Medical Engineering, a charity which designs gadgets and equipment for elderly and disabled people.

BIME is managed by the University of Bath, and is based at the Royal United Hospital.

One of the projects Mr Halsey has worked on is a paediatric wheelchair called Wizzybug, which is aimed at young children.

He said: "I'm really pleased to have been selected to represent the work design engineers are doing within the NHS.

"The Wizzybug project was a fantastic cross-disciplinary collaboration between key NHS staff, Whizz-Kidz, BIME, the University of Bath, and most importantly the children and parents who are now benefiting from this fun mobility solution."
