Hi – I’m an Assistant Professor of CS and Law at the Maastricht University Law and Tech Lab.

My research spans UX, privacy, consumer protections, and law. At present, I’m focusing on dark patterns and manipulative interfaces across multiple contexts – I also study surveillance technologies and privacy erosion.

Before joining Maastricht University, I earned my PhD in Cybersecurity at Northeastern University, advised by David Choffnes, Woodrow Hartzog, and Christo Wilson. In industry, I’ve interned at Common Sense Media’s Privacy Program, Vimeo’s Governance, Risk, Compliance, and Privacy team, and previously wrote docs for Rapid7 and Akamai Technologies (Network Standards). Academically, I’ve been a visiting PhD intern with Yixin Zou at the Max Planck Institute of Security and Privacy, and earned my M.S. in Cybersecurity as an ALIGN Scholar as well as a B.A. in Political Science & International Affairs at Northeastern University.

More info in my CV.

(If you’re wondering how to pronounce my name, I’ve gone by both American and European pronunciations of Johanna my whole life–both work!)
