March 24, 2015

Professor Sean C. Solomon and alumnus Carl Haber will deliver the keynote addresses at the 2015 Ph.D. and M.A. Convocation, respectively. The events will take place on Sunday, May 17 on the South Lawn of the Morningside campus.

Sean C. Solomon
Director of the Lamont-Doherty Earth Observatory
William B. Ransford Professor of Earth and Planetary Science

Solomon became Director of Columbia's Lamont-Doherty Earth Observatory in 2012 after serving for nearly two decades as Director of the Carnegie Institution's Department of Terrestrial Magnetism in Washington, D.C.  He earned his Ph.D. in geophysics at the Massachusetts Institute of Technology in 1971 and stayed on to teach and conduct research for two decades, running one of the earliest ocean-bottom seismometer labs. After moving to the Carnegie Institution in 1992, he served as principal investigator for Carnegie's part of the NASA Astrobiology Institute, which seeks to understand the origin of life on Earth and its potential to exist elsewhere.

Solomon is the principal investigator of NASA's MESSENGER mission to Mercury, leading the most comprehensive investigation of the closest planet to the Sun. In 2014, he was awarded the nation's top scientific honor, the National Medal of Science.  

Carl Haber
'80CC, M.A. '82, M.Phil. '83, Ph.D. '85, Physics
Senior Scientist, Physics Division, Lawrence Berkeley National Laboratory

Haber is a physicist at the Lawrence Berkeley National Laboratory in Berkeley, California. Since 2002, he has worked on digitally reproducing audio recordings from degraded and obsolete media. Collaborating with archivists and researchers across the country, Haber has given a new voice to historic artifacts by converting detailed imagery of microscopic grooves and lines into digital sound files. His accomplishments include playing back the oldest known human voice recording (a 10-second sample of the French folk song "Au Clair de la Lune" from 1860) and the only known recording of Alexander Graham Bell ("In witness whereof—hear my voice") dating from 1885.

In 2013, Haber was named a MacArthur Fellow. Awarded by the Chicago-based MacArthur Foundation every fall, the Fellowships recognize individuals of exceptional creativity, achievement, and potential from a wide range of disciplines.
