As long as I can remember I've been fascinated by beetles and their sheer endless variation in form and shape.

I was trained as a plant molecular biologist, my PhD thesis being on light-regulated gene expression in Arabidopsis. Since, I’ve been involved in such diverse topics as genetic modification of free amino acid content of starch potatoes, transcriptome analysis using DNA microarrays and the bioinformatics of metabolomics. Some years ago I realized one could rather quickly learn these skills, but becoming a taxonomic specialist is a more cumbersome and time consuming  task. Hence I decided to abandon all of these and to focus on my lifelong interest, the taxonomy of NW European Coleoptera, with an emphasis on the more ‘difficult’ groups, e.g. Hydrophilidae, Ptiliidae, Staphylinidae: Aleocharinae, Pselaphinae and Scydmaeninae.
