Scientific Director (Chairperson)

Prof. Dr. Wolfgang Schulz is director of the Leibniz Institute of Media Research | Hans-Bredow-Institut (HBI). He is also a professor for “Media Law and Public Law including Theoretical Foundations” at the Faculty of Law at Universität Hamburg. Furthermore, he was appointed director at Alexander von Humboldt Institute for Internet and Society in Berlin in February 2012.

Wolfgang Schulz works on questions of communications constitutional law, media law and internet governance (with a focus on intermediaries), legal problems of algorithmic decision-making and the ethics of digitalization. He often works at the interface between law and other disciplines such as communication science and computer science and with a focus on the dimension of knowledge. He uses the functional comparison of different national approaches to solve problems. The transfer to politics at all levels (state, federal, EU, Council of Europe, UNESCO) plays an essential role in his work.

He also coordinates the Content Contact Group of the Internet & Jurisdiction Policy Network (INJ). Wolfgang Schulz is a member of the Executive Committee of the Global Network of Internet and Society Research Centers (NoC). He is also head of the Board of Directors of the Hamburg-based citizens’ and educational channel TIDE and a member of the Board of Trustees of the #UseTheNews initiative.
