Former group members

Dr. Cyril Simon Wedlund

Cyril resides in University of Oslo
Cyril Simon Wedlund

Cyril holds a PhD in Astrophysics from the University Joseph Fourier of Grenoble, France (2006). He is currently involved in the ESA Rosetta mission to comet 67P/C-G with emphasis on the interpretation of ion and plasma measurements from the RPC suite of instruments by use of global hybrid simulations. His interests range from the modelling of electron and proton precipitation of solar origin in the atmospheres of the Earth, Mars and Venus to the physico-chemical processes at the origin of airglow and aurora in the solar system, using space-born (Mars Express, Rosetta, Cluster, DMSP) and ground-based (EISCAT, ALIS) instrumentation. He loves photography, music, science fiction literature, aikido and archery.

Working on: Hybrid model development, Photochemistry/Ionosphere module, mass-loading, data analysis and interpretation, Comets, Mars.
