Leon Thomsen
Scientist, Delta Geophysics
Executive Advisor, KMS Technologies
Research Professor, University of Houston
Visiting Scientist, Lawrence Berkeley National Laboratory

Leon Thomsen holds titles of Scientist at Delta Geophysics, Executive Advisor at KMS Technologies, Research Professor at the University of Houston, and Visiting Scientist at Lawrence Berkeley National Laboratory. He holds a B.S. in geophysics from California Institute of Technology (Pasadena) and a Ph.D. in geophysics from Columbia University (New York).

After several years in academia, Thomsen’s industrial career began in 1980 at Amoco’s research center in Tulsa, where he was the Amoco inventor of what is now called seismic AVO. He led significant revisions to the exploration seismic paradigm, helping to establish the basic ideas of polar anisotropy and azimuthal anisotropy. His 1986 paper, establishing the modern field of seismic anisotropy, is the single most-cited paper in the history of Geophysics. In 1995, he moved to Amoco’s Worldwide Exploration Group in Houston, where his 1997 paper established the modern field of converted-wave exploration.

At BP Thomsen investigated unconventional topics in geophysics; this led him, beginning in 2002, to controlled-source electromagnetics (CSEM). Working together with KMST, BP acquired and processed the world’s first successful at-scale tCSEM survey. In 2008 Thomsen retired from BP and established Delta Geophysics.

Thomsen has served the Society of Exploration Geophysics as Distinguished Lecturer, Distinguished Instructor, Vice-President, and President (2006-07). He holds the SEG’s Fessenden Award, and the Russian Academy of Natural Sciences’ Kapitsa Medal. He is an Honorary Member of the Geophysical Society of Houston and of the European Association of Geoscientists and is a Foreign Member of the RNAS.
