RACHELLCARROLL

I am Dr. Rachell Carroll, a geomechanical engineer and computational seismologist dedicated to decoding Earth’s fracture language through AI-enhanced fault dynamics modeling. As the Head of the Tectonic Futures Lab at Stanford University (2022–present) and former Senior Advisor to the USGS Earthquake Hazards Program (2018–2022), my work bridges deep learning, continuum mechanics, and field geology to predict fault rupture cascades and optimize subsurface engineering. By pioneering FaultFlow, a physics-informed neural operator that simulates fault zone interactions at petascale resolution with 96% accuracy across 200+ historic earthquake events (Science Advances, 2024), I have redefined how we anticipate seismic risks and design fracture-resistant infrastructure. My mission: To transform fault lines from threats into teachable systems, ensuring humanity builds in harmony with Earth’s tectonic pulse.

My previous relevant research includes "Critical Phase Transitions and Representation Reorganization in Deep Neural Network Training" (ICML 2022), exploring the relationship between sudden changes in model weights and performance leaps during training; "Neural Network Dynamics from a Complex Systems Theory Perspective" (Neural Computation 2021), applying self-organized criticality theory to understanding neural network training processes; and "Applications of Earthquake Prediction Algorithms in Model Anomaly Detection" (NeurIPS 2023), attempting to transform seismological methods into deep learning diagnostic tools. In earth sciences, I co-published "Multi-scale Modeling and Simulation of Fault Systems" (Journal of Geophysical Research 2022), establishing cross-scale models from microscopic friction to macroscopic fractures. These works have laid theoretical and methodological foundations for the current research, demonstrating my ability to combine geophysics with machine learning. My recent research "Phase Space Topology and Functional Emergence in Large Language Models" (Transactions on Machine Learning Research 2023) directly explores how fracture phenomena in language model training lead to the emergence of new functionalities, providing preliminary experimental evidence and analytical frameworks for this project.
