The Happier Lives Institute conducts research into the most cost-effective, evidence-based ways to increase happiness. We then share what we’ve found with donors and decision-makers so they can take action.
Staff

Dr Michael Plant
Founder and Director
Whilst studying for his PhD in moral philosophy at the University of Oxford, Michael realised there was a pressing need for more research on the most cost-effective, evidence-based ways to improve global happiness – he founded the Happier Lives Institute in 2019 as a result. As well as directing HLI, Michael is also a Research Fellow at Oxford’s Wellbeing Research Centre. Before that, he was a research assistant to Peter Singer, a researcher for the Rt Hon Sir Michael Fallon MP, and founded Hippo, a happiness-tracking app.
