Geology

Government of Greenland

I’m a geologist living in Nuuk and working as the Head of Department of Geology for the Government of Greenland. I have a PhD in Geology and a Masters in Science Communication and Public Engagement, both from the University of Edinburgh. I host Polar Podcasts, which airs weekly and explores personal stories of exploration of Greenland's remarkable geology from career Greenland geologists, from the 50s to the present. I also publish a weekly blog on life in Greenland as a foreigner.

Lead author, geologist Chris Yakymchuk working in the field in west Greenland.
