When I opened the door to the administration of the special committee on the 2016 Berlin attack for the first time in 2018, I glance at 4,500 folders with 690,000 pages of investigation records, emails, and police files. This first glimpse dates back two years when I started working for two members of parliament, jointly scrutinizing the most severe Islamist attack in Germany. Today, I am sitting in front of an air-gapped computer, fanning it thoroughly to prevent it from overheating. The machine runs my NLP-based analysis of all documents mapping the social network around the terrorist. The nebulous amount of files indicates how much (more) data security agencies have to processes in a digitised democracy. And: that parliamentary control over authorities require automated data analysis to persist in future.
Both insights – the challenge of digitization for security authorities, as well as the effective control over their work – typify my academic and professional interest: How should domestic security work in the digitised democracy?
Studying Public Policy at Columbia University's School of International and Public Administration (SIPA) in New York City and the Hertie School in Berlin, as well as working as an advisor to public players in the German security sector, I understood that the intersection of security policy, data science and policy implementation is a pivotal combination to address my questions. Inspired by my studies, freelance projects, and practical experiences, I wish to make the digitised democracy safer – without restricting freedom or curtailing the rule of law.
All-source intelligence analysts need improved modeling, analytic tools, and data visualization in order to understand dense urban areas and enhance situational awareness more effectively. POLassist helps you understand location data in an urban areas to improve situational awareness and response allocation. The POLassist prototype was developed as part of "Hacking4Defense" at Columbia University in the City of New York, 2020.
