Core team


Benjamin Todd

CEO and co-founder

Ben managed 80,000 Hours while it grew from a lecture, to a student society, to the organisation it is today. He has a 1st from Oxford in Physics and Philosophy, has published in Climate Physics, once kick-boxed for Oxford, and speaks Chinese, badly. Before 80,000 Hours, he was the first undergraduate to intern as an analyst at a top investment fund. Rather than taking the job, he persuaded the Chairman to donate £60,000 to get us off the ground.


Prof. Will MacAskill

Co-founder and President

In 2009, Will co-founded Giving What We Can, a leading charity evaluator that has raised over $400m in pledged donations to effective charities and advised the UK government, World Bank, Oxfam among others. In 2011, he co-founded 80,000 Hours with Ben. Currently an Associate Professor of moral philosophy at Oxford, Will has pledged to give over half his income to charity, and is the author of *Doing Good Better*.


Rob Wiblin

Director of Research

Rob studied both genetics and economics at the Australian National University on a national scholarship, graduating top of his class and being named Young Alumnus of the Year in 2015. He ‘earned to give’ as a research economist in various Australian Government agencies, and then moved to the UK to work at the Centre, first as Research Director then Executive Director, then as returned to research at 80,000 Hours. He was also a founding board member of Animal Charity Evaluators and a member of the World Economic Forum’s Global Shapers Community.


Roman Duda

Roman did a fully-funded Masters in Philosophy at Oxford, during which he also consulted for a major energy company on their business strategy, whilst also studying Mandarin Chinese. With a strong interest in Quantified Self, he has worked at the start-ups Memrise and Self Spark.
