Joseph Byrnes

Joseph Byrnes is an Assistant Research Professor at Northern Arizona University, transitioning to UT Dallas. His research focuses on geophysics, seismology, and tectonics, particularly in seismic imaging of subduction zones, mantle dynamics, and lithospheric structure. He leads NSF-funded projects including studies on ocean-mantle dynamics using OBS data and collaborative SZ4D MultiArray initiatives.

Key research interests include crustal anisotropy, seismic attenuation tomography, and joint inversion methods applied to surface-wave and scattering data. His work addresses continental margins, cratonic structures, and volcanic systems like the East African Rift and Iceland. Byrnes employs advanced techniques such as transdimensional Bayesian inversion and machine learning for seismic data analysis.

Current grants include NSF awards for projects like 'Constraining ocean-mantle dynamics' and 'Data-driven optimization of SZ4D MultiArray.' He collaborates extensively as a Co-PI on multi-institutional initiatives. His fieldwork spans locations such as the Galápagos, Alaska, and the Indo-Burman margin, yielding insights into lithospheric architecture and mantle processes.
