Question: Matthias Mann worked with in a group at Yale University with the man who won a Nobel Prize in Chemistry and shared half of the award with who?

<P0-S0> Matthias Mann (born 10 October 1959) is a scientist in the area of mass spectrometry and proteomics. <P0-S1>  Born in Germany he studied mathematics and physics at the University of Göttingen. <P0-S2>  He received his Ph.D. in 1988 at Yale University where he worked in the group of John Fenn, who was later awarded the Nobel Prize in Chemistry. <P0-S3>  After a postdoctoral fellowship at the University of Southern Denmark in Odense he became group leader at the European Molecular Biology Laboratory (EMBL) in Heidelberg. <P0-S4>  Later he went back to Odense as a professor of bioinformatics. <P0-S5>  Since 2005 he has been a director at the Max Planck Institute of Biochemistry in Munich. <P0-S6>  In addition, he will also become a principal investigator at the newly founded "Novo Nordisk Foundation Center for Protein Research" in Copenhagen. <SEP> <P1-S0> Frederick Sanger ( ; 13 August 1918 – 19 November 2013) was a British biochemist who twice won the Nobel Prize in Chemistry, one of only two people to have done so in the same category (the other is John Bardeen in physics), the fourth person overall with , and the third person overall with two Nobel Prizes in the sciences. <P1-S1>  In 1958, he was awarded a Nobel Prize in chemistry "for his work on the structure of proteins, especially that of insulin". <P1-S2>  In 1980, Walter Gilbert and Sanger shared half of the chemistry prize "for their contributions concerning the determination of base sequences in nucleic acids". <P1-S3>  The other half was awarded to Paul Berg "for his fundamental studies of the biochemistry of nucleic acids, with particular regard to recombinant DNA". <SEP> <P2-S0> John Bennett Fenn (June 15, 1917December 10, 2010) was an American research professor of analytical chemistry who was awarded a share of the Nobel Prize in Chemistry in 2002. <P2-S1>  Fenn shared half of the award with Koichi Tanaka for their work in mass spectrometry. <P2-S2>  The other half of the 2002 award went to Kurt Wüthrich. <P2-S3>  Fenn's contributions specifically related to the development of electrospray ionization, now a commonly used technique for large molecules and routine liquid chromatography-tandem mass spectrometry. <P2-S4>  Early in his career, Fenn did research in the field of jet propulsion at Project SQUID, and focused on molecular beam studies. <P2-S5>  Fenn finished his career with more than 100 publications, including one book. <SEP> <P3-S0> James Edward Rothman (born November 3, 1950) is an American biochemist. <P3-S1>  He is the Fergus F. Wallace Professor of Biomedical Sciences at Yale University, the Chairman of the Department of Cell Biology at Yale School of Medicine, and the Director of the Nanobiology Institute at the Yale West Campus. <P3-S2>  Rothman is also concurrently serving as adjunct professor of physiology and cellular biophysics at Columbia University. <P3-S3>  and a research professor at the Institute of Neurology, University College London (UCL). <P3-S4>  Rothman was awarded the 2013 Nobel Prize in Physiology or Medicine, for his work on vesicle trafficking (shared with Randy Schekman and Thomas C. Südhof). <P3-S5>  He has also received many other honors, including the King Faisal International Prize in 1996, the Louisa Gross Horwitz Prize from Columbia University and the Albert Lasker Award for Basic Medical Research both in 2002.
