data lead Global Witness

Sam Leon leads Global Witness’s work on investigative data journalism and digital storytelling. His work focuses on using publicly available and leaked data to expose corruption. Recent projects include an investigation into money laundering at the Trump Ocean Club, Panama and an analysis of the corruption risk posed by anonymously owned homes in London. His work often focusses on helping journalists to exploit large datasets and as such he is interested in developing effective methods for data-centric collaboration. In 2017, he worked with MIT Media Lab to build an immersive storytelling tool specifically tailored for human rights organisations that is now used to publish interactive, longform journalism at Global Witness.
