Intro

In the final Stage Talk of the year, we learnt the mechanics of investigating trade data thanks to this week's guest, Bellingcat research consultant and self-confessed data nerd Katherine de Tolly. Using the example of opioid shipments from India to West Africa, Katherine talked us through the intricacies of import-export data and how to navigate the many data gaps/inconsistencies inherit in the system.

The talk was hosted by Charlotte Maher on Thursday December 4th 2025. Music featured is courtesy of Artlist.
