Catherine Clarke Fenselau (born 15 April 1939) is an American scientist who was the first trained mass spectrometrist on the faculty of an American medical school; she joined Johns Hopkins School of Medicine in 1968.〔 She specializes in biomedical applications of mass spectrometry. She has been recognized as an outstanding scientist in the field of bioanalytical chemistry because of her work using mass spectrometry to study biomolecules.〔 ==Early life and education== Catherine Lee Clarke was born on 15 April 1939, in York, Nebraska.〔〔(【引用サイトリンク】url=https://www.ushupo.org/About/USHUPONews/Vol4,Winter2013/MemberProfiles/tabid/165/Default.aspx )〕 She graduated from Bryn Mawr College in 1961 with an A. B. (bachelor's degree) in chemistry.〔 She received a Ph. D. in organic chemistry in 1965 from Stanford University, working with Carl Djerassi.〔 As a field, organic mass spectrometry was new and had great potential impact for the pharmaceutical industry. The mass spectrometer was a new tool for examining the structures of small botanical molecules. Djerassi's lab examined electron impacts on molecules, studying basic mechanisms such as fragmentation and hydrogen transfer. For her thesis research, Catherine made a series of deuterium labeled analogues of amines, alcohols, esters and amides.〔 She spent the next two years in postdoctoral positions, studying on a 1965-1966 fellowship from the American Association of University Women at the University of California, Berkeley with Melvin Calvin. In 1967 she worked at the NASA Space Sciences Laboratory with Melvin Calvin and A. L. Burlingame.〔 Calvin's lab was developing methods to be used in the analysis of lunar rock samples. Fenselau described an analysis technique for preparing lipid samples from moon rocks, before actual lunar samples were available for testing.〔 She married, first, Allan H. Fenselau, with whom she had two sons, Thomas and Andrew, and second, Robert J. Cotter. 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「Catherine Clarke Fenselau」の詳細全文を読む スポンサード リンク
