Short abstract
Seismic imaging and ultrasound imaging are both based on wave propagation in complex media. I will present high-resolution elastic-wave imaging and inversion for fracture detection in complex geothermal fields. In addition, I will present super-resolution ultrasound imaging and ultrasound waveform tomography for early detection and characterization of breast cancer and prostate cancer. This presentation will demonstrate that advanced imaging techniques can be used not only for natural resource exploration, but also for cancer imaging to save human lives.
Lianjie Huang is a Senior Scientist 5 at Los Alamos National Laboratory. His research encompasses high-resolution seismic imaging and inversion for subsurface resource/fracture characterization, and medical ultrasound imaging for early detection and characterization of breast cancer and prostate cancer. He is the first researcher bringing advanced seismic imaging/inversion techniques to medical imaging, starting in early 2000s. His super-resolution ultrasound imaging for microcalification detection in the breast achieves the spatial resolution of X-ray mammography.


Biography
Lianjie Huang obtained his PhD in Geophysics (1994) from the University of Paris 7/Institut de Physique du Globe de Paris, under supervision of Peter Mora and Albert Tarantola, after receiving his B.Sc. in Physics (1985) and M.Sc. in Mathematics (1989) from Peking University. His seismic research includes acoustic- and elastic-wave modeling, least-squares reverse-time migration, and full-waveform inversion in isotropic and anisotropic media with applications to subsalt imaging, geothermal energy, and geologic carbon storage. His medical research areas are super-resolution ultrasound imaging and ultrasound waveform tomography for early detection and characterization of breast cancer and prostate cancer. He has served as PI for numerous projects on seismic imaging and
medical imaging for more than $44M of funding supported by U.S. DOE and DoD. He has mentored 21 summer students and 22 postdocs. He has published more than 200 journal and proceedings papers. He is a member of the SEG Research Committee and its CO2 subcommittee and a member of the SEG Publication Committee/Book Editorial Committee.
