Antoine Guitton is receiving the J. Clarence Karcher Award in recognition of his significant contributions to exploration geophysics. Guitton received his Ph.D. in 2005 from Stanford University, where he worked in the Stanford Exploration Project (SEP) under Professor Jon Claerbout. He is currently employed at 3DGeo Development. Antoine was recognized by SEG in 1999 for the Best Student Paper presented at the Annual Meeting ("Robust and stable velocity analysis using the Huber function"). He received, in 2004, EAGE's Arie Van Weelden award, which recognizes outstanding young geophysicists.
Beginning in 2003, Guitton started to accumulate a very impressive record of scholarly publications in peer-reviewed journals and 14 papers have subsequently been published or are in press.
Biography Citation for the J. Clarence Karcher Award
Antoine Guitton is a superbly well-rounded young geophysicist. He quickly masters the fine points of seismic theory, but at the same time he has a keen sense of the practical relevance and limitations of the theory. He enjoys looking at both the hidden clues contained in field data as well as the fine details of a mathematical formula, but finds the biggest reward at the point where the two meet. Antoine presents his work in a clear and convincing manner, but he is also humble and never tries to outsmart his audience. As a senior graduate student at Stanford, he was generous with his time in mentoring less experienced students and successfully conducted many joint projects with them. Even now that he is working in the industry and has broader responsibilities at his company (3DGeo Development) he still finds the time and energy to follow graduate student research as a consulting faculty at the Stanford Exploration Project.
Antoine got his start in geophysics by studying at the Ecole de Physique du Globe in Strasbourg, France, where he received an engineering diploma and a M.Sc. in geophysics (1996). He then worked for the Compagnie Générale de Géophysique in Houston from 1997 to 1999, where he quickly learned about the practical challenges of seismic processing. He came to Stanford in the fall of 1998, where he received an M.Sc. (2000) and a Ph.D. in geophysics (2005).
He now works as a senior geophysicist in the research and development division of 3DGeo Development in Santa Clara, California.
As demonstrated by the wide range of topics covered in the exceptionally high number (17!) of refereed papers that Antoine has published in his relatively short research career, he has tackled many of the most challenging problems in reflection seismology. At the beginning of his career, he mostly focused on multidimensional signal processing applications, whereas more recently he has made important contributions to the field of seismic imaging.
During his studies at Stanford, Antoine pushed forward the boundaries of practical noise attenuation and robust optimization. In the area of noise attenuation, he has developed several multidimensional signal/noise separation algorithms (adaptive and pattern-matching) based on least-squares modeling of the noise and the signal. His research has led to impressive real data results for the subtraction of multiple- related noise that was modeled by the SRME method. He has also applied his noise-suppression methodology to a broad range of less conventional geophysical data sets, such as electro-seismic data and bathymetry data recorded on the Sea of Galilee.
In the area of robust optimization, he has extensively worked on numerical solutions to large-scale optimization problems based on the L1 and other norms that are more robust than least-squares. His paper Robust and stable velocity analysis using the Huber function earned the Best Student Paper award at the 1999 SEG meeting, and in 2004, the EAGE presented Antoine with the prestigious Arie van Weelden Award for his work on signal and noise separation and robust optimization, noting in particular that this work has resulted in a number of practical applications.
More recently, Antoine has been working on the next generation of algorithms for migration by wavefield continuation and inversion. He has contributed to the theory and practice of reverse time-migration by applying his multidimensional signal processing expertise to the crucial problem of removing the artifacts caused by spurious correlations at the point of imaging. He is currently working with several Stanford students to develop practical methods for addressing current shortcoming of imaging methods by developing computationally efficient approximations to full least-squares inversion that will improve the fidelity of seismic images.
In keeping with his balance as a geophysicist, Antoine enjoys life outside of geophysics, particularly adventurous sports such as rock climbing and paragliding.
