I am an independent scientist and self-employed editor/proofreader affiliated with a proofreading company. My hobbies include field biology, geology, and drawing.

A selection of the rock photos is on www.mindat.org. All the mollusc photos are on waarneming.nl or observation.org, and some are used for the species descriptions in the NDFF Verspreidingsatlas. Most of the grass photos are on waarneming.nl.
