Prof. Dr. Eberhard Grün (born 1942, in Germany) is a German planetary scientist specialized in cosmic dust research. He is an active emeritus at the Max Planck Institute for Nuclear Physics〔(【引用サイトリンク】 Cosmic Dust Group )〕 , Heidelberg (Germany), research associate at the Laboratory for Atmospheric and Space Physics (LASP) in Boulder (Colorado), and was a Professor at the University of Heidelberg until his retirement in 2007. Eberhard Grün has a leading role in international cosmic dust science since over 30 years. == Education == Eberhard Grün studied Physics at the University of Heidelberg and received his degree in 1968. After his studies he did his PhD in the Max Planck Institute for Nuclear Physics in Heidelberg, and he received his doctoral degree in 1970 from the University of Heidelberg. The topic of his thesis was "Mass Spectroscopy of Impact Induced Ions". From 1970 until 1974, he was a research assistant in the MPIK, developing dust detectors for spaceborne missions and doing research on impact ionization for these dust detectors. During this period, he spent 6 months as a visiting scientist at NASA Goddard Space Flight Center focusing on data analysis of cosmic dust experiments, and 6 months as a visiting scientist at the NASA Ames Research Center, doing research on hypervelocity impact phenomena. In 1974, he became a senior research scientist at the MPIK. Eberhard Grün habilitated in physics in 1981 at the University of Heidelberg and he became a lecturer ("Privat-Dozent") at this same University in 1983. In 1981 he went back to the US for 6 months as a senior research associate of the US National Research Council (NRC), while working at the Jet Propulsion Laboratory. There he concentrated on dust-magnetosphere interactions and on data analysis of the Voyager 2 spacecraft. This stay abroad was followed in 1982 by a 6-months stay at the Lunar and Planetary science Institute (LPI) in Houston, for studying dynamics of interplanetary dust. Since 1989 he is a professor at the University of Heidelberg. In 2000, he became researcher at the Hawaii institute of Geophysics and Planetology, at the University of Hawaii, Honolulu (until 2007), while remaining a senior research scientist at the MPIK. In 2004 Eberhard Grün was a visiting scientist ("Erskine Visitor") at the Physics and Astronomy department of the University of Canterbury, Christchurch, New Zealand where he gave several lectures on the solar system, orbital dynamics, and the cosmos.〔(【引用サイトリンク】 University of Canterbury )〕 In 2007 he became a research associate at the Laboratory for Atmospheric and Space Physics (LASP) of the University of Colorado in Boulder (USA).〔(【引用サイトリンク】 LASP CCLDAS Biography )〕 In 2007, he retired from the MPIK after having worked there for 37 years. He remains active in dust science as an emeritus at the MPIK, and as a research associate at LASP. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eberhard Grün」の詳細全文を読む スポンサード リンク
