By e-mail

Write a concise e-mail to I tend to respond within 24 hours.

Note that all mail containing executables and archives are automatically filtered and will not reach my mbox. I use  VERY strict spam filters. If you expect a response from me but you’re not getting it, your initial mail probably didn’t pass my filters. If you bug me more than once with unsolicited mail, you will be permanently blacklisted.

If you want to contact me on issues not related to work, please let me know and I will give you a separate e-mail address to use.

By phone

You can try to phone me at: +31 (0)53 489 8031. Incoming calls are redirected to one of our secretaries. There is also voicemail.

By making an appointment

Don’t ask when I’m available: I have lost almost complete control over my calendar. The best thing to do is to contact Miranda Davidson.
