Dr. Jochen Kissel received his Ph.D. from the University of Heidelberg in 1971. As PI he has flown time-of-flight mass-spectrometers for dust particle analysis on all close encounter missions to Comet P/Halley in 1986. From 1985 through 1990 he was Co-PI for the remote Laser-ionization Instrument LIMA on PHOBOS. He directed the in-flight control electronics and data collection work. From 1986 through 1992 he directed the work for a time-of-flight secondary ion mass-spectrometer CoMA for the US-German Mission CRAF. He leads the design and development of a large target area dust impact mass-spectrometer for general application. Among other awards, Dr. Kissel received the Yu.A. Gagarin 50 Years medal from the Federation for Space Research of the Soviet Union for Outstanding Contribution to the Exploration of Space and to International Cooperation, and an ESA achievement award for the PIA investigation on GIOTTO.
