David W. Simpson
President, IRIS Consortium,
David W. Simpson has served since 1991 as President of the Incorporated Research Institutions for Seismology (IRIS), a Consortium of more than 120 U.S. universities with research and education programs in seismology and 100 Foreign Affiliates. IRIS is supported by the US National Science Foundation to develop and maintain facilities for seismological research. IRIS programs include the Global Seismographic Network (GSN, operated in cooperation with the US Geological Survey) of 150 stations worldwide; a pool of 1000 portable instruments (PASSCAL); a Data Management System; a program in Education and Outreach; and the USArray component of EarthScope, a major NSF project to develop an observatory of geophysical instrumentation for detailed investigations of the structure and evolution of North America.  IRIS resources are used to support university and government investigations in earthquake studies, research on Earth structure and dynamics, and applications in nuclear test ban monitoring. 

Dr. Simpson received his PhD from the Australian National University in Canberra.  From 1974 to 1991, he was at the Lamont-Doherty Earth Observatory of Columbia University where he was Senior Research Scientist and Associate Director for Seismology, Geology and Tectonophysics.  His research interests have included the study of earthquakes triggered by the filling of large reservoirs, velocity structure of the mantle transition zone, the tectonics and seismicity of the northeastern US and Central Asia. He has participated in field programs on all continents, including the establishment of earthquake monitoring networks in Australia, New York, Tadjikistan, Kyrghyzstan and Egypt. He participated in immediate post-earthquake studies in California, New York, Egypt, Armenia and Georgia.
