Kristian Hassel
About
Kristian Hassel is professor and Head of herbarium TRH at the NTNU University Museum. He is a botanist with particular interest in bryophyte biosystematics and ecology and he is teaching floristics at NTNU Department of Biology. He is leading the work on evaluation bryophytes for the Norwegian red list and is the President of the Nordic Bryological Society. The main emphasis of his research is the biodiversity and history of the bryophyte flora at northern latitudes. This involves metabarcoding and macro fossil studies of lake sediments, current effects of climate change in the Arctic (Zackenberg and Kobbefjord at Greenland), as well as studies on species distributions (phylogeography and species distribution modelling) and speciation processes in Sphagnum. Conservation and restoration of mires in relation to carbon fixation is of growing interest. Through the Norwegian Taxonomy Initiative he aims at barcoding the main bulk of Norwegian bryophyte species.
