Dr. Hejun Zhu received $536,729 from the the National Science Foundation for his research on Developing a Multi-Parameter Seismic Model of North America. Dr. Zhu and his team are developing a multi-parameter seismic model that uses state-of-the-art full waveform inversion technology and high-quality waveform records that will help geophysicists to better investigate physical properties of the Earth. This study may allow scientists to infer distributions of temperature, water content, and deformation.
