Dr. Janhunen received his PhD on space plasma physics from University of Helsinki in 1994, the thesis topic was electrostatic simulation of ionospheric E-region irregularities and MHD simulation of ionosphere-magnetosphere coupling. Thereafter Janhunen started to develop a global MHD-based ionosphere-magnetosphere coupling model “GUMICS” which was essentially completed in 1999-2000 and is in active use today. Starting from 2000 he developed also hybrid plasma simulations for Mars and other unmagnetised planets, various other plasma simulations for auroral physics as well as analysed lots of satellite plasma physics data in collaboration with Swedish and other scientists. He also made some contributions to astrobiological fields and in 2006 led a collaborative study which formulated a biosphere-geosphere interaction model for the evolutionary pressure required for the birth of multicellular life. In recent years he has mainly worked with the electric solar wind sail deep-space propulsion method which he invented in 2004-2006.
