The world is changing. We¡¯re facing unprecedented challenges in public health, transport, the environment and housing. We need bright, creative innovators to help us find solutions to these problems. We cannot afford to leave half our talent pool untapped.

They¡¯re not just producing products in search of a market; they¡¯re finding solutions to real-world problems.?
