Will MacAskill is an Associate Professor in Philosophy at Lincoln College, Oxford, and author of "Doing Good Better: How Effective Altruism Can Help You Make a Difference". He also cofounded two non-profits: 80,000 Hours, which provides research and advice on how people can best make a difference through their career, and Giving What We Can, which encourages people to commit to give at least 10% of their income to the most effective charities. These organisations helped to spark the effective altruism movement.
