Mission statement

I am a physicist by training who has made the transition from the fundamental research setting of a physics laboratory to the clinical setting of a medical hospital. Using my background in experimental physics, I develop novel technologies to enable MRI for ocular conditions and apply them clinically. My innovations have become part of regular clinical care, saving the vision and eyes of many patients.

Currently, my research focuses on ocular oncology, such as MR-based ocular radiotherapy planning and non-invasive quantification of eye tumor perfusion. Additionally, my ambition is to develop methods to fuse optical and MR-imaging of the eye, enabling the next paradigm shift in the treatment planning and follow-up of intra-ocular tumors.

Personal activities

• Since 2005 various responsibilities in national and international committees of the Emmanuel Community, a Catholic association with over 12.000 members in 72 countries. I’m currently part of the Dutch national governance and a member of the international advisory council (since 2018, re-elected in 2021).
  Two examples of responsibilities that shaped my leadership and mentoring skills

  • I've set-up the Dutch version of the Zacchaeus Course, a programme which helps the participants discover how to achieve unity and coherence in their lives, between their Christian faith and their day to day actions.
  • I have been in charge of the national youth team for 2008-2012. Together with my wife, I was a mentor for the youth, guided the local youth teams and (co-)organized over ten journeys in- and outside of Europe (impression). After our service in the youth team, we were responsible for the community in the West of the Netherlands (until 2020).
• Since 2015 a board member of the Dutch chapter of Aid to the Church in Need, a charity with approximately 4-6 million Euro of donations annually.
