Carolus J. Schrijver is a Senior Fellow at Lockheed Martin Advanced Technology Center, California, where his work focuses primarily on the magnetic field in the solar atmosphere. His research includes the dynamics of the magnetic field at and above the solar surface, how that shapes the heliosphere, and how it powers solar eruptions that are the drivers of space storms around the Earth. Dr Schrijver is involved in several NASA missions to better understand the Sun and the heliosphere. He is co-editor of the first three books in this series, and has published a popular science book entitled Living with the Stars on the multitude of connections between the human body, the Earth, the planets, and the stars.
