Biennial Award (now the R. Bruce Lindsay Award) and in 2006 received the ASA Silver Medal in Physical Acoustics. He was Director of the 1994, 1996, 1998, 2000, 2002, 2004, and 2006 Physical Acoustics Summer Schools. Dr. Bass has served in an advisory capacity for a number of organizations including the Physics Division, National Research Council of Canada, U.S. Army Atmospheric Sciences Laboratory, Northrop Corporation, Textron Defense Systems, General Dynamics, University of Tulsa, NASA Langley Research Center and the U.S. Army Research Laboratory.
Douglas P. Drob received a Bachelor’s
degree in Engineering Physics from
Embry-Riddle Aeronautical University
in Daytona Beach, FL in 1991 and a
Ph.D. in Atmospheric and Space
Science in 1996 from the University of
Michigan, Ann Arbor. Since then he
has worked as a Research Physicist at
the Space Science Division of the Naval
Research Laboratory, Washington, DC.
His research involves the statistical analysis and interpretation of satellite- and ground-based measurements that improve the fundamental understanding of the Earth’s upper atmosphere. These activities provide physical knowledge and meteorological information to improve infrasound propagation models in sup- port of international nuclear treaty monitoring efforts.
Catherine de Groot-Hedlin received a Ph.D. in Earth Sciences in 1991 from the University of California, San Diego, and is currently a project scientist at the Scripps Institution of Oceanography. Her research inter- ests include the propagation of acoustic energy in the ocean and the atmosphere, with application to ver- ification of the nuclear test-ban treaty, and the analysis of hydroa- coustic signals from underwater
earthquakes. She is a member of the American Geophysical Union and the Acoustical Society of America.
Milton Garcés is the Director of the Infrasound Laboratory (ISLA) of the University of Hawaii at Manoa. The ISLA is involved in multidiscipli- nary applied research projects in volcanology, oceanography, meteorolo-
gy, and just about anything big that blows up.
