Charles Langmuir is a solid Earth geochemist who carries out reserach on diveres aspects of the plate tectonic geochemical cycle, including ocean ridges, convergent margins and intraplate volcanism. He has led or participated in 20 cruises to ocean ridges, including the first investigation of the Arctic Ocean ridge system. With Peter Huybers he has proposed close linkages between volcanism and glacial cycles both on land and undersea which has led to widespread interest and controversy (voice.fas.harvard.edu). Charlie was the principal investigator for PetDB, the pioneering geochemical data base (www.petdb.org). He was one of the founders of the journal Geochemistry, Geophysics, Geosystems ("G-Cubed" www.g-cubed.org ) a leading journal of the American Geophysical Union.
With Wally Broecker Charlie published How to Build a Habitable Planet (www.habitableplanet.org) which conveys the history of Earth from the Big Bang to humankind in a form that can be used as a textbook and also is accessible to the interested public. The book receiced Honorable Mention for the Prose Award as one of the best Earth science books published in 2012 from the American Publishers Association.
For his scientific contributions Charlie has received the Bowen Award from the American Geophysical Union, the Arthur Holmes Medal from the European Union of Geosciences for outstanding international contributions to solid Earth science, and the Urey Medal from the European Union of Geochemistry for outstanding contributions to geochemistry over a career. He was elected to the American Academy of Arts and Sciences and 1998, and the National Academy of Sciences in 2006. He is a Fellow of the American Geophysical Union and the Geochemical Society.
Charlie received his B.A. from Harvard University in 1973, and Ph.D. from the State University of New York at Stony Brook in 1980. He has been at Harvard since 2002, after 20 years at Columbia University's Lamont-Doherty Earth Observatory.
