Joe Dellinger received a PhD in 1991 from Jon Claerbout’s Stanford Exploration Project. He then did a three-year post-doc at the University of Hawaii before joining Amoco in Tulsa in 1994. He moved to BP in Houston in 1999 and has worked there since. In his career he has specialized in anisotropy, multi-component algorithms and processing, and most recently investigating the problem of how to record ultra-low frequencies with the goal of enabling inversion algorithms like FWI to resolve complex velocity-model-building challenges in deep-water marine environments.
