2021-04-27: We're searching to fill a tenure track position in seismology.
2021-03-12: New paper Ground Deformation After a Caldera Collapse: Contributions of Magma Inflow and Viscoelastic Response to the 2015–2018 Deformation Field Around Bárðarbunga, Iceland led by Siqi Li, U Iceland, published in JGR today. The paper explores the how and whether post-eruptive inflation-like volcano deformation signal can result from viscoelastic relaxation following eruptions (maybe) and how deep magma inflow coupled with reversed slip on caldera faults can create deformation signal similar to that caused by shallow magma inflow using data from Bárðarbunga's 2014-2015 eruption.
2021-02-22: We've implemented a pod for the community-wide Unlearning Racism in the Geosciences (URGE project: ... follow along as we're working on the deliverables.
2021-02-03: We've gotten a recruitment video for the Solid Earth Geophysics group at UAF made:
2020-05-15: New paper Unexpected large eruptions from buoyant magma bodies within viscoelastic crust published in Nature Communications today.
2020-02-06: I put a preprint of a book chapter on GNSS here. Comes with some overview on the theory, and plenty of applications.
2020-02-02: Decadal-scale aquifer dynamics and structural complexities at a municipal wellfield revealed by 25 years of InSAR and recent groundwater temperature observations, published in WRR (for a while already).
