WaLSA Team | Shahin Jafarzadeh

Shahin is a research scientist at Max Planck Institute for Solar System Research, MPS (Göttingen, Germany) and an affiliated researcher at Rosseland Centre for Solar Physics, RoCS (Oslo, Norway). His studies concern the Sun's lower atmosphere, 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.
