Speaker: Professor Maarten de Hoop, Rice University


We present an overview of advances in the study of inverse problems in exploration seismology with an emphasis on anisotropic and nonlinear elasticity, and (multiple) scattering. We discuss uniqueness results with geometric data, time-domain or high-frequency waveform data, and finite-frequency or time-harmonic data on the one hand, and novel reconstruction procedures on the other hand. We touch upon the conditional Lipschitz stability estimates (well-posedness) underlying robust iterative regularization, techniques from boundary control and scattering control disentangling internal multiple scattering without knowledge of the wave speeds and interfaces, elasticity in Finsler geometry, and nonlinear interaction of distorted plane waves with  discontinuities in the nonlinear material parameters generating quasi-internal sources. We conclude with some emerging directions at the intersection of deep learning and inverse problems.
 
Speaker Biography: Professor Maarten de Hoop, Rice University
Maarten de Hoop is the Simons Chair in Computational and Applied Mathematics and Earth Science at Rice University, where he leads the Geo-Mathematical Imaging Group research consortium.  His research interests are in inverse problems, microlocal analysis and computation, and applications in exploration and global seismology and geodynamics. In addition to appointments at Rice and Purdue, he has been on the faculty of Colorado School of Mines, Massachusetts Institute of Technology, and the Graduate University of the Chinese Academy of Sciences Beijing (visiting faculty). He has served as senior research scientist and program leader with Schlumberger Gould Research Center and is scientific advisor since 2010 with Corporate Science and Technology Projects, Total American Services, Inc. Maarten received his Ph.D. in technical sciences from Delft University of Technology in the Netherlands. In 1996 he was awarded the J. Clarence Karcher Award (Society for Exploration Geophysicists).
