Davidson Inventors Challenge

The annual competition empowering the next generation of innovators

The Davidson Inventors Challenge is an annual competition for Year 11 and 12 students from across schools in the UK to channel their creativity and passion for STEM (Science, Technology, Engineering, and Mathematics).

Hosted by the Department of Chemical Engineering and Biotechnology (CEB), in collaboration with the Association of Science, Technology & Innovation – ASTI and supported by the Institution of Chemical Engineers (IChemE), this challenge is more than just a competition – it's an opportunity to be part of something bigger.

At the heart of the Davidson Inventors Challenge is a passion to inspire the next generation of innovators and problem solvers to create solutions to some of the world's biggest obstacles. Centred on the Sustainable Development Goals (SDGs) set by the United Nations, entrants are asked to reflect on the urgent need to address some of the most pressing global challenges, from climate action to clean water and sanitation, and to propose a cost-effective and considered response.

By participating in the Davidson Inventors Challenge, you won’t just be competing – you’ll be learning, growing, and contributing to a global cause. You’ll gain invaluable experience in Chemical Engineering and Biotechnology, two fields at the forefront of solving today’s most critical issues.

Through this challenge, you’ll develop essential skills such as problem-solving, critical thinking, and teamwork. These are not just skills for the competition – they are skills for life.

Honouring the legacy of a pioneer

The Davidson Inventors Challenge is named after Cambridge University Emeritus Professor John Davidson, the founding father of fluidisation.

Launched in 2020, the Davidson Inventors Challenge is a competition and outreach initiative encouraging innovation in STEM. We honour Professor Davidson's legacy each year by inviting students in Years 11 and 12 to research sustainable development goals, select a problem to address, and present an innovative, sustainable solution that can make a positive global impact.
