Media Appearances (old)

I appear regularly in national media to provide context and expert commentary on privacy, security and human rights. If you want to know whether I’m available for guest appearances and commentary, you can always contact me.


At the height of the Cambridge Analytica scandal I was asked to appear on Dutch current events program Nieuwsuur to provide context and commentary on Facebook’s data collection practices and their privacy implications.


When a new bill on the national intelligence services was put forward I was interviewed on my research on supervision of intelligence services in national newspaper De Volkskrant.


I gave a television interview condemning the practice of the Dutch police to surveil climate activists and their families.


I reacted to the Dutch Cybersecurity Strategy in De Volkskrant, arguing that offensive information security researchers should be better protected.


I provided expert commentary on the privacy issues involved with parents sharing data of their children online for a column in NRC (Dutch).

I don’t find it far-fetched that in the near-future you will be able to extrapolate from a baby’s face what they will look like as an adult.


In response to revelations that Dutch intelligence services had been wiretapping a human rights organisation I wrote an editorial in favour of encryption for NRC (Dutch).

After all as an attorney you have a special responsibility to offer clients a safe haven. If clients can’t speak freely about their case, then their attorney can’t defend them properly.


As the Dutch government responded to accusations of possible espionage by banning certain hardware manufacturers, I argue in favour of focusing on encryption instead in my analysis of our response to vulnerabilities in IT-infrastructure in national newspaper de Volkskrant (Dutch).
