As Naturalist, I study historical bird-collections. With help of colleagues at Naturalis and from museums worldwide as with scientist around the globe, I am involved in a number of research projects. 


I’m working on some identification issues, like those of Long-tailed Tits Aegithalos caudatus and some other groups. Also participating in a worldwide NGS research of all Numeniinae. And working on three possible undescribed taxa.


Other researches are focussed on early Australian bird collections, the Cook voyages around the globe, and the History of the Muséum national d'Histoire naturelle. The early collection from Naturalis, is also part of my interest.


In the past years I did several presentations on The Ornithology of the Baudin expedition (1800-1804) (Prague, London, Leiden, Adelaide and Erfurt). I succesfully defended my thesis (The Ornithology of the Baudin expedition (1800-1804)) at 22 May 2018 (Leiden University).
