The Geo-Mathematical Imaging Group
Purdue University's College of Science and the Department of Mathematics manage the
Geo-Mathematical Imaging Group (GMIG). It is an industry and government funded,
multi-disciplinary, inter-institutional graduate education and research program.
Founded in 2007, the group works to develop improved technology to meet the complex challenges
of modern day prospect evaluation, enhanced oil recovery, CO
2 sequestration,
and general geological study of the Earth's subsurface by expanding the
boundaries of knowledge of seismic imaging, inverse scattering and tomography
through collaborative scientific activities and breakthroughs.
In the research program of the Geo-Mathematical Imaging Group,
exploration seismology meets global seismology, integrating passive
source, ambient-noise source with active source and controlled-noise
source imaging. It consists of integrated analysis and very large scale
computation with strongly interconnected theoretical, and algorithmic
and HPC projects.
In industry, GMIG is currently best known for its:
- massively parallel structured direct solver for the
3D Helmholtz equation
- convergence theorems and strategies for nonlinear FWI
- multi-scale nonlinear compression and sparse sampling: theory
and algorithms for the scattering and reconstruction of
waves in connection with minimal data acquisition strategies
- acoustic and anisotropic elastic (artifact-free) RTM-based inverse
scattering
- DG-method based digital (reservoir) rock, acousto-elastic
and diffuse electromagnetic wave physics
