Welcome !

The Sun facilitates life on Earth through the radiation energy, but it also emits the solar wind, which impacts the Earth’s space environment giving rise to the beautiful auroras at northern and southern high latitudes, but also geomagnetic storms that can harm humans and infrastructure in space and on ground. Studying the ways the Sun impacts the near-Earth space and the upper atmosphere is an important element of understanding the universe we live in, but also key for mitigating the adverse effects the harsh space environment can create.

Our group’s research focuses on physics of the Solar-Terrestrial interactions using ground-based and space-borne measurements together with the Space Weather Modeling Framework (SWMF) global geospace simulations.

I am a professor at the Department of Climate and Space Sciences and Engineering, and currently also the department chair. I joined the University of Michigan in 2018, attracted by the versatile research program in the department covering climate and space sciences, space instrument development and operations, data analysis and world-leading space environment modeling.

I came to Michigan from Finland (Northern Europe), where I worked at Aalto University and prior to that at the Finnish Meteorological Institute

Our research group works in collaboration with our local colleagues at the University of Michigan, but also interacts with leading groups in the US, in Finland, and elsewhere in the world.
