I work in the Space Physics Research Group at the Space Sciences Laboratory , University of California, Berkeley , where I study the near-space environment of Earth and Mars, using plasma observations from the THEMIS, Cluster, Wind, Geotail, Lunar Prospector, and Mars Global Surveyor spacecraft.
Before I came to Berkeley I worked at the International Space Science Institute (ISSI) in Bern, Switzerland, and in the Plasma and Space Physics Group at the University of Oslo, Norway.
