Jeff Welker - UArctic Chair University of Oulu
Jeff Welker has been studying Arctic plant & ecosystem ecology, biogeochemistry and biosphere-atmosphere interactions since his research activities at NyAlyesund, Svalbard and Abisko, Sweden started in 1990. His research program focuses on four themes: a) tundra plant and ecosystem structure and function now and in the future using the ITEX (International Tundra Experiment) program; b) the Arctic Water Isotope Cycle and sea ice controls on shifting patterns, sources and distribution of precipitation; c) terrestrial and marine food web processes focused on diets and space-use of wolves, polar bears, brown bears, caribou and reindeer and d) herbivore and climate effects on greenhouse gas emissions, sources and ages. Dr. Welker serves on the US Arctic Icebreaker Coordination Committee (AICC), the NSF Office of Polar Programs Advisory Committee and as the Arctic Research Advisory to the Chancellor at the University of Alaska Anchorage. He is convening a UArctic Congress 2018 session on caribou-reindeer-cultural practices and is leading a new project titled: “Pan Arctic Water Isotope Network” which was granted INTERACT remote access to research stations. The project involves colleagues from Iceland, Denmark, Greenland, Czech Republic, Poland, USA, Finland, UK, Canada and Norway.


The UArctic Chair Jeff Welker's food web program on Polar Bears is featured in Arctic Today, sharing that high PFAS levels found in Barents Sea polar bears. This collaborative program lead by Jeff's Norwegian colleagues has been underway for many years and it reflects the breadth of the Chairship & research program.  In...

UArctic Chair Dr. Jeff Welker and colleagues in Finland and across the Arctic have received Academy of Finland (AoF) funding and EU INTERACT support to study the changing Arctic water cycle. 

As part of his UArctic Chairship, Professor Jeff Welker has completed establishing his first core set of collaborative, interdisciplinary research projects in Finland at the University of Oulu. This article will explain the first of two projects.

Professor Jeffrey Welker from the University of Alaska Anchorage was recently appointed as the first UArctic Chair, with the position hosted by the University of Oulu. In this introduction he shares his concerns regarding the future of the Arctic, and what his priorities are in his new role.
