Congratulations, Jiaqi!
Congratulations to Dr. Jiaqi Li who has been offered a faculty position as Assistant Professor at Peking University! This is very well-deserved. Good luck with your new adventures!!
Paper Submission
A paper entitled “Azimuthal Anisotropy From Multimode Waveform Modeling Reveals Layering Within the Antarctica Craton” by Beghein and Xu was submitted to the new journal Seismica for publication. Preprint available at 10.5281/zenodo.8346552
Promotion!
C.B. was promoted to Full Professor!
LPI Webinar
C.B. had a great time presenting her group’s research about Mars to the LPI via Webinar. Her talk was titled “Seismological Constraints on Mars Interior Structure: Results from the InSight Mission”
