2024-present. Public and Professional Speaking. 

My work on Sovereign Citizens is driven by an ongoing dialogue with professional stakeholders and society more broadly. I regularly lecture before Dutch professional audiences (e.g. Ministry of Finance 2024; Bailiff Society 2024; Internal Revenue Service 2025), offer workshops to the judiciary (twelve times in 2024–2025), and collaborate with government officials at state (Bureau for Scientific Research; Support Network for Civil Unrest) and local (various municipalities) levels. For some examples of public conversations, see my appearances at the Dutch House of Representatives 2025 (link); at Radboud Reflects 2025 (link); in an NPO 1 Radio Interview 2025 (link); on the UG Faculty of Law Podcast 2025 (link); at UU Studium Generale 2024 (link); on the Podcast De Jortcast 2024 (link); and on a Dutch Judiciary Podcast 2024 (link; all in Dutch). 

2023-present. Media Appearances.

On account of my work on Sovereign Citizens (summed in this video), I frequently comment on recent developments in written and televised media, for instance on the recent appearance of Sovereign Citizens within Dutch law enforcement. For some of these media appearances, see here (Volkskrant 2025), here (RTL Nieuws 2025),  here (EenVandaag 2025), here (NPO Radio 1: Misdaadbureau 2025), here (NPO Radio 1: Vroeg 2025), here (NPO Radio 1: dr. Kelder & Co 2024), here (EenVandaag 2024), here (nu.nl 2024), here (WOS 2024). I have also been interviewed on my work on Sovereign Citizens  here (University Magazine 2024), here (UKrant 2024; photo to the left), and here (Friesch Dagblad 2024;  for a conversation in the University Newspaper about my book project on the witness, in a series called "The Breakthrough", see this link (all in Dutch).

2023-present. Popularizing Writing.

I frequently discuss my research in more popularizing venues. In two contributions, for example, I discuss the why of courtroom symbols. Focusing on the judicial robe (here) and the scales of justice (here), I show how these persistent symbols and attributes aim to cover up the arbitrariness which is always implied when someone exercises authority over another. For a popularizing appraisal of sovereign citizens' philosophical claims, focusing on legal personhood and the social contract, see this 2023 blog (link); for brief review articles targeting a broader audience see this piece I wrote for Sociale Vraagstukken in 2025 (link) and this blog I wrote for the UG's Faculty of Law (link).
