Paul G. Richards
Paul G. Richards (born March 1943 in Cirencester , Gloucestershire ) is a British-American geophysicist ( seismics ).
Richards studied at Cambridge University with a bachelor's degree in mathematics in 1965 and at Caltech with a master's degree in geology in 1966 and a doctorate in geophysics in 1970 (dissertation: A contribution to the theory of high frequency elastic waves, with applications to the shadow boundary of the Earth's core ).
In 1971 he became an Assistant Professor, 1976 Associate Professor and 1979 Professor of Earth Sciences at Columbia University . Richards was Professor of Earth and Environmental Sciences from 1996 until his retirement in 2008. From 1980 to 1983 he headed the Faculty of Earth Sciences and was Associate Director of the Lamont-Doherty Earth Observatory . From 1987 he was Mellon Professor of Science at the Lamont-Doherty Earth Observatory at Columbia University.
In 1993/94 he was on a sabbatical at the US Arms Control and Disarmament Agency, in 1989/90 at the Lawrence Livermore National Laboratory , in 1997 at the Los Alamos National Laboratory and in 1977/78 as a Guggenheim Fellow in New Zealand. In 1977 he attended the Institute for Earth Physics in Moscow and in 1983 he was visiting professor in Beijing
He quantitatively examined the effects of diffraction, attenuation and scattering on the shape of seismic waves and is known for developing seismic methods for studying nuclear weapons tests (since 1985 he has been on the Seismic Review Panel (SRP) of the US Air Force Tactical Applications Center (AFTAC) )). Among other things, he found evidence of a rotation of the inner core of the earth with waves from nuclear weapon tests.
In 1993 he became a Fellow of the American Association for the Advancement of Science and in 2008 of the American Academy of Arts and Sciences . From 1992 to 1994 he headed the seismic department of the American Geophysical Union , of which he has been a fellow since 1977.
In 2006 he received the Leo Szilard Lectureship Award . He is a fellow of the American Physical Society . In 2010 he received the Harry Fielding Reid Medal from the Seismological Society of America.
In 1980 he became a US citizen.
