I am a scientist working at the Finnish Meteorological Institute. I majored in theoretical physics at the University of Helsinki in 1999-2011 for my MSc and PhD.
The research I am involved in at the FMI deals with the interaction between Earth-like planets (here my favourite planet is Venus) and the solar wind. We are concentrated on the numerical modelling of the plasma interactions of planetary objects without a strong intrinsic magnetic field. The lack of intrinsic field means that the interaction happens directly with the upper atmosphere of the planet. In contrast, Earth has a strong intrinsic magnetic dipole and the solar wind interaction takes place far away from the atmosphere. The Venus-solar wind interaction is one of the scientific themes of the European Space Agency's Venus Express spacecraft. The interaction is observed using the spacecraft's plasma package (ASPERA-4 particle instrument) and the magnetometer. VEX has been orbiting the planet since April 2006.
We model the planetary solar wind interactions with a numerical simulation code on a super computer enviroment. The code is developed at the FMI and a lot of my work deals with the details of the code. The code allows us to model the whole interaction in 3D and to treat ion kinetics and electrodynamics self-consistently. As a result, we can use the simulation results to interpret the spacecraft observations in global context.
