Onderzoek
interesse

In het algemeen wens ik bij te dragen aan onze kennis over de wereldwijde biodiversiteit en evolutie van zoetwater-, mariene en terrestrische platwormen (Platyhelminthes, Tricladida).

De geografische schaal van mijn onderzoek is over het algemeen mondiaal of betreft in ieder geval grote delen van de wereld. Beoordelingen van mondiale hotspots op het gebied van biodiversiteit zijn vertekend doordat de minder charismatische ongewervelde dieren, zoals platwormen, over het algemeen worden verwaarloosd, hoewel ongewervelde dieren de belangrijkste deel van de biodiversiteit vormen.

Hoewel dit op zich al interessant is, kunnen deze dieren ook goede modelorganismen zijn om terrestrialisatie (het aan land gaan) tijdens de evolutie te bestuderen. De terrestrialisatie van dierlijk leven van voorouders in zee of zoetwater is een belangrijke overgang in de geschiedenis van het leven. Planaire platwormen (Platyhelminthes, Tricladida) vormen een ideale groep modelorganismen om deze kolonisatie van het land te bestuderen, omdat ze vertegenwoordigers in zowel zoetwater als de zee hebben, en soorten die op het land voorkomen.

De methodologie betreft een integratieve benadering van taxonomie, systematiek en fylogenetica, waarbij morfologie/anatomie meestal gecombineerd wordt met moleculaire karakters.

Carrière

Begonnen als prille vogelaar op zevenjarige leeftijd, terwijl ik in mijn bootje roeide tussen de moerassen en weilanden ten noorden van Amsterdam, ben ik uiteindelijk afgestudeerd aan de Universiteit van Amsterdam met als hoofdvak ornithologie. Aan het einde van mijn master kwam ik echter ook de groep triclad platwormen tegen, waarnaar ik mijn wetenschappelijke en professionele aandacht verlegde. Hoewel ik nooit zal stoppen met het kijken naar vogels, drong het tot me door dat ongewervelde dieren eigenlijk het grootste deel van de biodiversiteit uitmaken en dat er nog veel te ontdekken valt over hun taxische diversiteit. En daarom nam ik triclad platwormen aan als modelorganismen om de evolutie, fylogenie en biogeografie van een geselecteerde groep ongewervelde dieren te bestuderen.
