Torkild Bakken
Background and activities
Assosiate professor at NTNU University Museum since 2006, and I was Head of Department (Department of Natural History) 2010-2018.
Research
My research interests are in systematics and biogeography, particularly of polychaete worms (Polychaeta) and sea slugs (Nudibranchia). The main interest is in phylogeny, taxonomy and distribution within these groups, but I do also have a broad interest in faunistics and biodiversity of marine invertebrates in general, in Norwegian waters, coastal as well as deep-sea. Part of my research is linked to NTNU's strategic thematic area Ocean Science and Technology, and the AUR-lab.
Teaching
I am currently teaching in the courses "Faunistics and floristics" (BI1002) (marine part), and "Marine biodiversity" (BI2036). Previously I taught in "Biogeography and biosystemtics" (BI2001) and "Archaeological oceanography" (ARM3030). I supervise master students in systematics and in marine biology, the latter usually as a part of the AUR-lab.
Scientific collections
I am senior curator and responsible for the Museum's collections of marine invertebrates.
Current research projects:
- Biosystematics of Nereididae and Sphaerodoridae (Polychaeta)
- Taxonomy and biogeography in polychaetes in the Norwegian waters
- Mapping and taxonomy of polychaetes in the Norwegian Sea (PolyNor)
- Taxonomy and biogeography in sea slugs (Nudibranchia) in Norwegian waters
- DNA barcoding - polychaetes, nudibranchs and skates
