    Responsibilities: Research Zoologist, Curator of Polychaeta

    Education: Cand. mag. and cand. real. University of Bergen, Norway
    Ph.D. University of Southern California, Los Angeles

    Research Interests: Systematics, phylogeny and taxonomy of annelids, specifically the marine groups that used to be called Polychaeta. I have spent about 50 years working on these worms, and have participated in making it obvious that the polychaetes are a paraphyletic assemblage of annelids! Currently focusing on the scale worm family Polynoidae, which includes a large number of species commensal with all sorts of other invertebrates.

    Professional Activities: Mostly in the past as officer at various levels in such societies as the Southern California Academy of Sciences, Biological Society of Washington, Society for Systematic Zoology and American Society of Zoologists (currently Society for Integrative and Comparative Biology).
