Dr Michael Plant
Founder and Research 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.

Dr Ryan Dwyer
Senior Researcher

His prior projects have explored the relationship between happiness and meaning, the impact of technology on our social lives, and the effect of volunteering on well-being.
