My work focuses on developing and applying machine learning and computational methods to scientific problems.

I’m also interested in language models and broader problems in modern machine learning.

Selected Research

2026 · Published · Machine learning · Earth Systems and Environment

Seven-Day Landslide Forecasting

Uses PCA-reduced InSAR histories and a random forest to forecast landslide instability seven days ahead, asking whether noisy satellite deformation can support short-horizon prediction rather than retrospective detection.

Under review · Computational science

Shear-Band Prediction and Relocation

The undeformed glass contains enough structural information to predict where its shear band will form. Softening a targeted region before loading can then move the eventual band to a different location.

Under review · Machine learning

Weak-Form Physics-Informed Learning

Weak-form constraints transfer derivatives from noisy data to smooth test functions, stabilizing inverse parameter recovery in scientific imaging problems where pointwise physics-informed losses amplify noise.

Seven-Day Landslide Forecasting from PCA-Derived InSAR Data with a Random Forest Classifier

Combines PCA-reduced InSAR deformation histories with a random forest to forecast instability seven days ahead. The study asks whether satellite displacement signals can support short-horizon prediction, rather than only retrospective detection.

2.5 CNN: Leveraging 2D CNNs to Pretrain 3D Models in Low-Data Regimes for COVID-19 Diagnosis

Uses 2D CNN pretraining to give a 3D CT model a stronger starting point when labeled volumetric data are scarce. The method was developed for COVID-19 diagnosis, where full 3D training sets are relatively small.

Weak-Form Physics-Informed Neural Networks for Noise-Robust Inverse Problems

Weak-form constraints transfer derivatives from noisy data to smooth test functions, stabilizing inverse parameter recovery on scientific imaging problems where pointwise physics-informed losses amplify noise.

Covert-Channel Forensics of Deceptive Language Models: When Internal-State Monitoring Adds Admissible Evidence

Internal activations add evidence when deceptive or collusive information is hidden from the transcript. When visible behavior already reveals it, white-box probes add much less beyond the behavioral evidence.

Computational science

Modified-Equation-Informed Solution-Discrepancy Signatures Detect Hidden Stabilization Changes in Convective Heat-Transfer Solvers

Small stabilization changes can leave heat-transfer outputs nearly unchanged even when the solver has changed. Modified-equation signatures reveal those hidden numerical changes directly from the computed solution fields.

Computational science

Emergence of a Deterministic Butterfly Cone in Structural Glasses

A localized perturbation spreads through a structural glass inside a deterministic butterfly cone. Its speed changes little as structural relaxation slows dramatically, separating information spreading from glassy dynamics.

Computational science

Predicting and Relocating the Shear Band in a Two-Dimensional Model Glass

The undeformed glass contains enough structural information to predict where its shear band will form. Softening a targeted region before loading can then move the eventual band to a different location.
