Greg Davies

Greg B Davies is a globally recognised expert in applied behavioural finance, sustainable investing, and the science of better decision-making.

For over two decades, Greg has worked at the intersection of psychology, finance, and technology—helping individuals and organisations overcome the biases, noise, and emotional hurdles that stand in the way of better choices. He combines rigorous academic insight with a gift for making complex ideas practical, engaging, and often unexpected.

In 2006, Greg founded the first behavioural finance team in global banking as Barclays’ Head of Behavioural Quant Finance. Today, he leads Behavioural Science at Oxford Risk, building technology that helps people make smarter financial decisions at scale. He holds a PhD from Cambridge in Behavioural Decision Theory and has advised many of the world’s largest financial institutions.

Greg has delivered keynote talks and his acclaimed behavioural wine-tasting experience, Pour Better Decisions, on six continents—for audiences including global banks, investment firms, hedge funds, regulators, family offices, and wealth management client events. Whether speaking to investors, leaders, or advisers, his sessions equip audiences with the tools to be more consistent, confident, and clear-headed in their decisions.

He has lectured at Imperial College and LSE, and held associate fellowships at Oxford’s Saïd Business School and UCL. He is co-author of Behavioral Investment Management, and his online course, The Art of Behavioural Investing, distils decades of research and experience into practical steps to improve long-term financial decisions by understanding your own psychology.

Beyond finance, Greg is a passionate advocate for the arts. He chaired Sound and Music, the UK’s national organisation for new music, for five years, and co-created Open Outcry, a ‘reality opera’ set on a live trading floor. He’s also an experienced choral singer and a frequent speaker on decision-making, music, and creativity.
