I'm Will MacAskill, Associate Professor in Philosophy and Research Fellow at the Global Priorities Institute, University of Oxford. My academic research focuses on the fundamentals of effective altruism - the use of evidence and reason to help others as much as possible with our time and money - with a particular concentration on how to act given moral uncertainty. I am the author of the upcoming book What We Owe The Future. I also wrote Doing Good Better and co-authored Moral Uncertainty. I am the Director of the Forethought Foundation for Global Priorities Research, a co-founder and the President of the Centre for Effective Altruism (CEA) and I helped to create the effective altruism movement. CEA supports hundreds of effective altruism local groups, hosts regular effective altruism conferences, and providing online resources and forums for discussion. I also co-founded 80,000 Hours, a YCombinator-backed non-profit that provides research and advice on how you can best make a difference with your career, and Giving What We Can, a global community of effective givers that is best known for The Giving What We Can Pledge to give 10% of lifetime income to the most effective charities.
