William Helland-Hansen joined the Department of Earth Science, University of Bergen, in 1997 after 12 years at Norsk Hydro (Research Centre 1985-1995, Production 1995-1997). From 1998 he has been a full professor at University of Bergen and from 2007 an adjunct professor at the University Centre of Svalbard (UNIS).

His research covers a wide range of aspects related to clastic sedimentology. Main research topics are sequence stratigraphy, trajectory analysis, clinoform dynamics, source-to-sink, shallow-marine sedimentation, spatial and temporal structure of basin fills, and coastal change in the 21st century. His research data have been gathered primarily from the Norwegian Shelf and Svalbard. William has participated in many larger projects, as project leader and principal investigator.  Through his career he has been the main supervisor for more than 50 MSc students and 10PhD candidates.  

In addtion to his research, William has a special interest in public outreach connected to  the natural history of his home region. He was the chief editor of the bestseller Naturhistorisk Vegbok, Hordaland ("Natural History Pathfinder for Hordaland") and has been the editor of the follow-up webside grind.no. https://www.grind.no/en

 

  • Initiator, chief-editor and project leader of the book project Natural History Pathfinder for Hordaland (“Naturhistorisk Vegbok, Hordaland”)(Nord4, 2004) which is a popularised presentation of bedrock geology, quaternary geology, zoology, botany and meteorology, applied to the region of Hordaland, Western Norway. The book contains 568 pages and 1750 illustrations, was published October 2004, and has been a local best-seller (20 000 copies sold).
  • University representative and project participant in the establishment phase for the science centre in Bergen, VILVITE, opened May 31st, 2007. VILVITE is a centre for informal learning with the goal to increase the recruitment to natural sciences. In the project I was in charge of the weather and climate section (one of three focussed themes for the centre), scientific co-editor for all exhibits (about 80) and the editor for all labelling and textual information that went into the centre.
  • Co-editor and from 2013-2020 project leader and editor of the portal of GRIND (http://grind.no/) at the University of Bergen – a new platform and digital gateway to “man and landscape”; a canal to the researchers and the sources of knowledge built on the books Cultural History and Natural History Pathfinders for Hordaland (released December 2016).
  • Co-editor “Ei halvøy i Hardanger” (Nord4, 2013). Stories about nature and culture at Neshalvøya, Hardanger, Western Norway. This book is a close-up look into all aspects of nature at this small peninsula, ranging from plants to animals, geology and cultural history. 150 pages.
  • From 2014 member of editorial board of “Naturen”, Norway’s oldest popular science magazine
  • 2017-2018 Leader of team developing new exhibitions in geology for re-opening of the Natural History Museum, University of Bergen
