Last updated January 1, 2024.

I hold a permanent research staff position at the Eindhoven University of Technology. I receive a steady salary and my work is not funded through a specific grant or company. I write and speak on a range of topics I care about, and when I do, I represent no one except myself. I’m in compliance with my employer’s disclosure and conflict of interest policies, and will remain so.

Occasionally, I collect royalties from the sale of books or articles. I’m committed to making my research and writing available online for free and open-access. I sometimes earn speaking fees and/or receive travel expenses for running workshops or speaking at an event. I have been paid to consult on matters related to my work, although only rarely.

When I am paid to speak or write an article, I will contract as to subject matter (e.g., design research, design tools, creative technology, software engineering, etc.), but not as to substance. If I mention or use any products or services in my work, it’s because I deem them appropriate.

I’m co-founder and managing director of UXsuite GmbH, Cologne and own shares in this company. Also, I’m part of the Bassfrucht creative collective, from which I do not earn money. Apart from that, I don’t have specific investments (aside from index investments, the details of which I do not keep track of). I hold a patent, which is currently being commercialized, but I do not have any financial or professional stake in this.

Any other relevant activities outside of TU/e or financial interests that could bias my work will be continuously disclosed on this site.

This disclosure statement follows the practice of Kate Darling, Jonathan Zittrain, Terry Fisher, Lawrence Lessig, David Weinberger, and John Palfrey.
