Leaf is a nonprofit that supports exceptional teenagers in exploring how they can best save lives, help others, or change the course of history. Each summer, we run four free, 5-week online fellowships that combine Oxbridge-style learning, thought-provoking content, and a community of smart, curious, and ambitiously altruistic peers. Whether you’re diving into global priorities in The Mathematics of Morality, applying scientific thinking in Biology for a Better Tomorrow, learning from the past in History to Shape History (for the better), or tackling urgent questions in Dilemmas and Dangers in AI, each programme is designed to help you explore how your skills and interests could make a real difference.
Accepted applicants gain access to facilitated tutorials, mentored projects, and Q&As with professionals working on some of the world’s most pressing challenges, plus possible grant funding to pursue impactful follow-up projects. All applicants are given access to our self-guided online courses. We aim to equip young people not just with knowledge, but with the tools, community, and confidence to take bold and meaningful action—this summer and beyond.
