Tijmen Jan Moser received his Ph.D. from the University of Utrecht, concentrating on the shortest-path method for seismic ray tracing. He has worked as a geophysical consultant for a number of companies and institutes, including Amoco, Institut Français du Pétrole, Karlsruhe University, Bergen University, Statoil/Hydro, Geophysical Institute of Israel, Fugro-Jason, and Horizon Energy Partners. Moser was an Alexander-von-Humboldt stipendiat 1996- 1997. Since 2005, he has been working independently with SGS-Horizon, Seismik, and many other associations. Based in The Hague, The Netherlands, he is close to the former estate of Christiaan Huygens, whom he considers the greatest geophysicist of all time. Moser's main interests include seismic imaging, asymptotic methods, seismic reservoir characterization, diffraction, and geothermal exploration. He has authored many influential papers on ray theory and ray methods, Born inversion and modeling, macro-model independent imaging, and diffraction im
