WaLSA Team | Shahin Jafarzadeh

Dr. Shahin Jafarzadeh is a scientist at Leibniz Institute for Solar Physics — aka KIS — (Freiburg, Germany) and an affiliated researcher at Rosseland Centre for Solar Physics, RoCS (Oslo, Norway). His studies concern the lower-to-mid atmosphere of the Sun, regarding how magnetic fields structure dynamics of those layers — towards understanding the mysterious heating of the solar atmosphere, particularly from wave activity. He is a founding member of the WaLSA team and a member of a number of international committees. He is an experienced observer, who also passionately engages in public outreach activities.
