Campaign and messaging strategy
I'm an LSE-award-winning behaviour change expert. I write campaign plans and core messaging, plan actions, and handle press for campaign groups, local parties, candidates, and civil society groups in the UK and the Netherlands. After four years advising governments worldwide on what makes people change their minds, I now put that to work on the ground, running campaigns with Fossil Free London and the Green Party in Tower Hamlets.
Actions I have worked on, in different roles. On some I did the strategy and the planning, on others the press or the photographs.
Reports I co-wrote at the Behavioural Insights Team. Essays and opinion pieces I publish will appear here as they come out.
I campaign locally in East London, planning actions and managing press for Fossil Free London, alongside building the local organising infrastructure for the Green Party in Tower Hamlets. For the Greens, I oversee the support network for local representatives, managing the team that tracks resident issues, coordinates community responses, and runs public communications for the borough's councillors. Before this, I spent four years (2022–2026) advising governments, regulators, and international organisations on human behaviour and what makes people change their minds.
