Professor, from the University of Oslo’s Institute of Theoretical Astrophysics, is the author of over 160 scientific articles with more than 2,200 citations. Prior to becoming an affiliate scientist in 2011, Viggo spent a considerable amount of time at HAO conducting research on solar wind acceleration and coronal heating, mostly with former director Tom Holzer and senior scientist Philip Judge.

In recent years Viggo has invested a significant amount of his time developing the three-dimensional radiation magnetohydrodynamics (MHD) code "Bifrost" (in Norse mythology Bifrost is the path from the mortal world to that of the Gods). Bifrost has provided invaluable physical insight into the triggering, formation, and appearance of chromospheric spicules, as well as the passage of Alfvénic waves through the outer solar atmosphere. During Viggo's affiliate scientist appointment, he is helping us improve our understanding of chromospheric magnetism and dynamics as part of Frontier One in HAO’s 2011–2015 Strategic Plan.
