A fierce Viking at heart, Sigurgeir enjoys musicals, Eurovision and the Great British Bake-off. He holds degrees in biochemistry and molecular biology, computer science and medical life sciences from the University of Iceland. Prior to joining the group, Sigurgeir worked in deCODE Genetics in Iceland on polygenic risk scores and GWAS. He still won’t shut up about how much better the food was there, although whenever he brings Icelandic delicacies to the (computational) lab, it stinks for days afterwards. Sigurgeir now studies somatic mutations and germline copy number variation in inflammatory bowel disease.
