66th London International Youth Science Forum

66th London International Youth Science Forum (LIYSF) will take place from 23rd July to 6th August 2025.

LIYSF is an accredited not-for-profit social enterprise founded in 1959, in the aftermath of the world wars, to give young people from all nations a deeper insight into science for the benefit of humankind. The two-week residential event is held annually at Imperial College London and attracts 500 of the world’s leading young science and engineering students aged 16-21 years old from more than 80 countries, across six continents. LIYSF is passionate about empowering students to think globally and use science to tackle problems such as sustainable energy, food and water security, global health, climate change and biodiversity.

LIYSF enjoys the Patronage of HRH The Princess Royal since 2020, and founding Patron in 1959, HRH The Duke of Edinburgh. We also have the support of the UK government, British Council and patronage and support from UNESCO. Please see our website for further information: www.liysf.org.uk

The majority of participants are supported to attend the forum as prize winners of national and international science competitions. Many also receive scholarships from educational bodies, schools and colleges, grants from industry and scientific institutions and funding from charitable foundations. The participation fee of £3,295 for the 14 day programme, covers all accommodation, meals, full programme costs, scientific visits and free travel to programmed events in central London.
