Research interests

I am a physicist combining simulations, routinely utilizing the largest supercomputers worldwide, with data-driven techniques and theoretical analysis to tackle some of the grand challenges of geophysics, including uncovering the physical mechanisms relevant to understanding earthquakes, tsunami generation and seismic shaking.

I am the recipient of a AGU Macelwane Award and an AGU Fellow, a current Thomas and Evelyn Chancellor’s Endowed Faculty Fellow in Geosciences in the SIO Department, and the president of the EGU Seismology Division.

Congrats, Dr. Rekoske!

Huge congratulations to John Rekoske on successfully defending his PhD! This is a special milestone for John and also for me personally because John is the eighth PhD student graduating from my group but the first through IGPP. More photos on LinkedIn.

SeisSol and ExaHyPE Workshop

I can hardly believe it has been 20 years of SeisSol and 10 years of ExaHyPE development! To mark these anniversaries, Michael Bader, Tobias Weinzierl, and I are hosting a Scientific Workshop, Training, and Hackathon at the LRZ in Garching near Munich on June 11–12, 2026.

Congrats, Dr. Wirp!

Big, big congratulations to Dr. Sara Aniko Wirp! Aniko defended her thesis "Modeling of Large Megathrust Earthquakes and Tsunami Generation using High-performance Computing“. The 7th student graduating from my group and the first to graduate while on parental leave. Kudos, Aniko!

ACM Gordon Bell Prize

We were awarded the "Nobel Prize" of Supercomputing, the Association for Computing Machinery (ACM) Gordon Bell Prize at SC25 for our paper “Real-Time Bayesian Inference at Extreme Scale: A Digital Twin for Tsunami Early Warning Applied to the Cascadia Subduction Zone”

Hyperion Award for "Best Use of HPC in Physical Sciences"

Thank you Hyperion Research for awarding us the 2025 HPC Innovation Excellence Award for “Exploring Real-Time Tsunami Warning System on World’s Fastest Supercomputer” at SC25!

HPCwire Reader's Choice Award for "Best Use of HPC in Physical Sciences"

Thank you to the HPCwire readers for the “Best Use of HPC in Physical Sciences” award!

In the SSA News!

Nice story in the SSA News on the Paul Andrew Spudich Fund supporting group members Jeena Yun's and Baoning Wu’s travel to Japan, to attend the slow-to-fast workshop. Look out for the featured “happy” Easter egg in Spudich & Frazer (1984)!

CRESCENT Annual Meeting

Inspiring subduction science in Seattle, and great to present new dynamic rupture models for Cascadia, the first fully coupled earthquake-tsunami benchmarks and global analysis of kinematic coupling models at the CRESCENT (Cascadia Region Earthquake Science Center) annual meeting with Fabian Kutschera and Bar Oryan.

Congrats, Dr. Niu and Dr. Schliwa!

Very proud to congratulate Zihua Niu and Nico Schliwa on the successful defense of their PhD theses, both awarded the highest distinction, summa cum laude.
It has been such a privilege to advise them, witness their growth as scientists, and to celebrate this milestone together.
Congrats Dr. Niu and Dr. Schliwa!

Tandem Hackathon

Our first Tandem Developer's Hackathon has concluded successfully. Thanks to all participants for making it happen! Tandem is a scalable discontinuous Galerkin code on unstructured curvilinear grids addressing linear elasticity problems and sequences of earthquakes and aseismic slip. Watch out for new features, releases, and papers at Tandem's GitHub repository: https://lnkd.in/grfcdaTA.

Science paper - Small and Large Earthquakes Don't Play By the Same Rules
