I'm a behavioural scientist. I spend my days working out what everyday, large-scale data can tell us about how people behave — and when I'm not doing that, I like to play music.

By day I lead behavioural science at Lloyds Banking Group, somewhere in the overlap between psychology, economics, and machine learning. A lot of my research uses anonymised banking data from millions of people to spot things that are hard to see any other way — like how gambling tracks with health and wellbeing, or the small financial changes that can appear years before someone starts to lose the ability to manage their own money.

What gets me up in the morning (aside from my young daughters' terrible sleeping habits) is the opportunity to make a real difference in people's lives through this work — by understanding and supporting our often all-too-human decision-making.

I did my PhD in Psychology at Warwick and still work with colleagues there and at Nottingham and Exeter. Some of it has ended up in Nature Human Behaviour, JAMA Network Open and the Journal of Finance, and fed into the UK's review of gambling. A few of those papers are below — and the music is further down.
