My research focuses on bryophyte systematics and 'hidden biodiversity'. I study evolutionary relationships and species delimitation of bryophytes, from tropical forests to polar tundras. I am interested in unravelling the hidden biodiversity of bryophytes and lichens, soil bacteria and fungi, and airborne biological particles, in natural and urban ecosystems.

Research
interest

I use an integrative taxonomic approach to study the evolution and diversity of bryophytes, and contribute to comparative biodiversity assessments and genetic biomonitoring.

Main research topics:

  • I study systematic relationships and character evolution, mainly in the Dicranidae, one of the two largest lineages of mosses (ca. 4000 species). 
  • I clarify species delimitations and improve species identification of bryophytes by DNA barcoding, to assess and monitor biodiversity. Examples are bipolar bryophyte species and the Dutch bryoflora.
  • I contribute to species inventories, unravelling soil and airborne biodiversity by DNA metabarcoding, and analyses of spatial biodiversity patterns. Examples are Atlantic island bryophytes and Antarctic biodiversity. 
  • I lead the interdisciplinary HiddenBiodiversity project, which studies urban biodiversity in Dutch cities; for more information see
