Our group at the Department of Climate and Space Sciences and Engineering focuses on physics of the Sun-Earth interactions using ground-based and space-borne measurements together with global space weather simulations. Our research group collaborates with our local colleagues at the University of Michigan, but also interacts with leading groups in the US and elsewhere in the world. The links provide more information about auroras and space weather.
