He had joined SEP in 1991 and received a Ph.D. in geophysics in 1995. Previously he received a B.S. in physics with minors in mathematics and computer science from Iowa State University in 1974, and an M.S. in geophysics from Stanford in 1994.
From 1974 to 1991 he worked for Western Geophysical, the last six years in the Houston research department. He worked for Shell Exploration and production technology from 1995 to 1997, and then moved to the ARCO Exploration Research and Technical Services in the Seismic Acquistion and Processing group as a senior research geophysicist until ARCO was acquired by BP. Ray was a Senior Research Geophysicist in BP's EPT Advanced Imaging group from 2000 to 2018.
His present interests involve simultaneous source acquisition and processing, coded airgun (Popcorn) acquisition and processing, prestack migration-velocity determination, signal and noise attenuation, especially multiple attenuation, and the data processing applications of multi-dimensional prediction. He is a member of the EAEG, SEG, GSH, and SIAM.
He presented the 2015 EAGE Distinquished Lecture on Simultaneous Source Processing and Acquisition and the 2017 SEG Distinquished Lecture on Simultaneous and Coded Seismic Sources.
