Henning Kuehl is receiving the J. Clarence Karcher Award in recognition of his outstanding research abilities and an uncompromised willingness to share his knowledge with the geophysical community. A native of Germany, Henning received his BSc in geophysics from The Technical University of Clausthal and his PhD in geophysics from the University of Alberta, under the supervision of Mauricio Sacchi. Kuehl's thesis, on the development of least-squares migration as an extension of conventional migration, was called a potential technological breakthrough.

Biography Citation for the J. Clarence Karcher Award

It is a real pleasure to write this citation for Henning Kuehl, one of this year's recipients of SEG's J. Clarence Karcher Award. This award recognizes his contribution in the area of seismic imaging and inversion.

A native of Germany, Henning received a bachelor's degree in geophysics from The Technical University of Clausthal in 1998. Prior to commencing his studies in geophysics, Henning worked as a paramedic in the Hannover area. In September 1998, he arrived at the University of Alberta to begin his pursuit of a doctorate in applied seismology. From the very first day, Henning demonstrated excellent research abilities. He was instrumental in starting a new industry sponsored group at the University of Alberta (The Signal Analysis and Imaging Group). In less than a year Henning brought the group to a high level of understanding in the theory of seismic imaging and began developing new technologies to enhance the resolution of prestack depthmigrated images. Over the course of his PhD research, Henning combined inverse theory, signal estimation theory, and seismic imaging theory to develop wave-equation methods for imaging irregular and inadequately sampled data. In addition, Henning conducted important studies that showed that regularized migration/inversion can also be used to obtain robust estimates of amplitude variation with angle (AVA) gathers in media with complicated velocity structure.

Henning has already proven himself an excellent researcher with great insight into wave propagation phenomena, signal theory, and practical problems of seismic data processing; but he is also a scientific mentor for new students in the Signal Analysis and Imaging Group. He has demonstrated remarkable maturity as a researcher, as shown by his efforts to develop new research projects for the group, and by working diligently to help other students and academic staff achieve their research goals.

Henning received his doctorate in September 2002. His external reviewer, Laurence R. Lines of the University of Calgary, provided the following comments: "Henning Kuehl's PhD thesis is one of the most innovative and important geophysics theses that I have seen in the last decade. His development of least-squares migration as a method for extending conventional migration to the true inversion domain shows considerable promise as a technological breakthrough. It could be a major step in our desire for true amplitude migration".

Henning has five peer-reviewed publications (two in GEOPHYSICS) and six publications in SEG Expanded Abstracts. He has also presented his work at the EAGE, CSEG, and JSEG meetings. His research has been recognized by the CSEG– two of his presentations received The Chairman Award at the 2001 CSEG convention in recognition of his high-quality work in seismic imaging. He also received The Graduate Student Scholarship from the Canadian Petroleum Producers Association in both 1999 and 2000.

Henning has now joined Shell Canada in Calgary. Henning is the epitome of an outdoorsman, spending most weekends skiing in the Canadian Rockies. In his day-to-day interaction with others, Henning demonstrates a profound respect for different ideas, beliefs, and ways of life. All these qualities, combined with a great sense of humor, make Henning a truly pleasant colleague.

We applaud him on this recognition and wish all the best in his new endeavors. We sincerely believe that we will see further technical and scientific contributions from him in the future.
