Taxonomic term: Nematoda [WoRMS]

Diversity and evolution of nematodes, their interactions with other organisms, origin of symbiosis and parasitism. are the main subjects of my research. Up to date, I described ten new genera and 109 new species, accompanied by taxonomic revisions and identification keys. Phylogenomics of free-living nematodes and application of metabarcoding in assessing the resilience of ecosystems are of particular interest. My publication list accounts for over 160 papers, including journal articles, book chapters, teaching manuals, museum catalogues, popular publication, etc. During my research career, I participated in four collaborative projects focusing on nematode systematics. My own research on the diversity of Swedish nematodes received continuous financial support from the Swedish Taxonomy Initiative since 2011. I organized or participated in scientific expeditions in the Ukraine, USA, Argentina, New Zealand, Sweden and New Caledonia.

In 2015 I started as a taxonomic editor of NeMys/WoRMS, focusing on several groups of free-living nematodes. Same year I received LifeWatch Data Grant to revise one of the nematode orders that now includes about 700 species. Work included updating of all existing and addition of new species records, addition of environmental data, type localities and original descriptions. The work continues, although at a slower pace, and with different focus.

The scope of WoRMS is continuously expanding beyond the taxonomic checklist. New features are being added and the database becomes more integrated with other biodiversity resources. As a result, its user base will continue to grow beyond the community of taxonomists it was originally aimed at. One of my current strong interests is to expand the currently limited set of identification keys for nematodes available as part of NeMys/WoRMS and improve the functionality of the underlying software.
