Young Scientists for Africa provides scholarships for talented African science students to attend the annual London International Youth Science Forum

Our Mission

YoSA provides a scholarship scheme for young African scientists to attend the London International Youth Science Forum (LIYSF), focusing on individuals for whom other financial support is not available. Each year these African scholars join 500 of the best science students from across the globe for a two week summer school, learning from world-leading scientists through lectures, debates and visits. The forum provides YoSA scholars with life-changing knowledge and contacts which will empower their science careers and help address the critical shortage of scientists in Africa. YoSA is also developing a network of student science communities to help support the next generation of African scientists. Over the past 5 years, and despite Covid interuption, we have supported a number of students from over 5 African countries to attend LIYSF, either by travelling to London or virtual attendance.

Scholarship Opportunity

All sponsorship funding is controlled within the UK and YoSA offers to fund a number of students to attend LIYSF from within Africa each year. YoSA offers full and partial scholarships. A full scholarship covers both LIYSF participation charge and also return flights to London, a partial scholarship will cover the LIYSF participation charge, but not return London flights. Please note below exclusions for all scholarships.

The funding covers:

London International Youth Science Forum

The London International Youth Science Forum (LIYSF) is a two week residential student event hosted at Imperial College London, with lectures and demonstrations from world-leading scientists, visits to pioneering university laboratories, research centres and UK scientific institutions. Annually, LIYSF attracts 500 leading young scientists aged 16-21 years old, from 75 countries across the globe. Students are able to tailor their programme at LIYSF to suit their STEM interests. There is a strong and active social calendar at LIYSF. A vital part of the experience of attending LIYSF is teaching and learning about different cultures and traditions. Further details can be found at
Attending LIYSF has a huge personal impact on and benefit for the individuals that attend. They have the opportunity to meet peers from around the world and learn about developing scientific initiatives and technologies used worldwide and bring them home. This encourages students to consider new areas of scientific and combined scientific disciplines and broadens the international outlook of the attending students, forging international networks that will be invaluable in their careers in supporting international collaborations in future research.

Whilst LIYSF welcomes students from over 70 countries across the world and from each continent, Africa is not currently well represented.  LIYSF is looking to work over the coming years to change this and establish better and sustained international representation across Africa. To date, YoSA has provided scholarships to students from Kenya, Rwanda, Zimbabwe, Tanzania and South Africa. These students were the only representatives from their countries, and were such excellent representatives for their regions and countries that some have been invited back to join the LIYSF student counsellor team this year. YoSA has identified LIYSF as a key platform to help achieve its charitable aims and shares with LIYSF the ambition to increase the representation of attendees from across Africa.
