Rolf builds systems to detect and measure harmful and illegal content on social media. This work presents distinct challenges: social media data is quickly removed from platforms, presented in visual formats, and often appears in multiple languages beyond English. The latest AI models show great promise in addressing these obstacles, opening up opportunities to develop tailored systems that can detect information-based threats and harm quickly and precisely.
Besides being affiliated with the Psychological Defence Research Institute, Rolf is the director of Markolo Research, a data science consultancy. Previously, he was Principal Scientist at the Technical and Scientific Development Branch of the NATO Strategic Communications Centre of Excellence in Riga, Latvia. While there, he led the Centre's research into bots and trolls on social media, which was published quarterly under the title Robotrolling. He holds degrees from the University of Cambridge, the University of Oxford, and Trinity College Dublin.
