As of 2021, I am a 51 year old married man from the Netherlands, father of two sons (Ruben (21), Matthias (18), and a daughter Anna (13)). I am married to Sandra and live in Gouda.
Most of my childhood was spent in the Netherlands. But I also spent 6 years in Sri Lanka, the Maldives, Kenya and the United States during my teenage years. I studied Business Administration at the Rotterdam School of Management.
I work at Kennisnet and am responsible for our Open Domain advocacy). The Kennisnet Foundation is a public Dutch organisation which is publicly funded and has the goal to be "THE dutch organisation for ICT use in Education". Apart from being responsible for our "consumer" services I am very involved in the Wikiwijs project which aims to encourage Dutch teachers to develop and share Open Educational Resources.
Through my work at Kennisnet I have been involved with Wikimedia since February 2005.On December 15th, 2006, I became part of the Board of Trustees of the Wikimedia Foundation as an appointed member. After several years as a vice-chair I became the chair from 2013 until 2015. I departed the board in December 2015 after serving 9 years as a board member.
After a decent "Wiki-break" I joined the board of the Dutch chapter in 2019. I am currently the chair of the Dutch chapter. Spend a lot of my time on the Wikimedia European Affiliates Cooperation (https://meta.wikimedia.org/wiki/Wikimedia_European_Affiliates_Cooperation) and the new capacity exchange project (https://meta.wikimedia.org/wiki/The_Capacity_Exchange)
