Phylogenomics of free-living nematodes and application of metabarcoding in assessing the resilience of ecosystems are of particular interest. Now I teach nematode identification to researchers from various disciplines who want to use nematodes as their study objects. I started as a taxonomic editor of Nemys (World Database of Nematodes) in 2015. Same year I received LifeWatch Data Grant to update part of the database: taxonomy, environmental data, type localities, original descriptions. My current priorities include unification of free-living and parasitic nematodes in Nemys, promotion of the use of Nemys/WoRMS taxonomy in research  projects and databases, expansion and improvement of identification tools available in Nemys/WoRMS.","AbstractOtherLang":null,"AbstractLangCode":null,"AbstractLangID":null,"AutID":128724,"ND":"2015-02-23","UD":"2017-10-16","ORCID":"0000-0002-4285-0754"},"loaninfo":null,"pictures":[],"institutes":[{"instituterec":{"OrderNr":1,"Acronym":"NRM","ENFunction":null,"InsIDtmp":4481,"OrigNameLangCode":"sv","OrigNameLangID":53,"FullOrigName":"Naturhistoriska Riksmuseet","InsID":4481,"Function":null,"BeginDay":null,"BeginMonth":null,"BeginYear":null,"Begindate":"","Enddate":"","PIAdrID":157746,"AdrID":123172,"Line1":null,"Line2":null,"Line3":null,"Line4":null,"Phone":null,"GSM":null,"Email":"oleksandr.holovachov@nrm.se","EnvName":"Sweden","EncAddress":"Research Dept.,, P.O.
