Ollie is currently finishing his PhD at the Oxford Department of International Development, where his research focuses on leveraging computational methods to understand the drivers of insurgent recruitment in Turkey. A quantitative social scientist by training, he is interested in the use of remote sensing and spatial data science to analyse the social world. 

Ollie is a big fan of open source software development, research, and investigative work. He built an image processing library in Python that uses deep learning to turn unstructured image data into a social network graph based on co-appearance in photographs. He also occasionally writes for Bellingcat, and recently co-wrote an open source investigation into pollution by multinational oil companies in Iraq. In his free time, he writes blog posts on all things spatial, from building a 3D model of the Beirut explosion to using street lamps to correct visual bias in election maps.
