Sparse-view photoacoustic reconstruction

Testing when a learned reconstruction beats model-based inversion, and why it fails under distribution shift.

Synthetic inverse problem comparing Tikhonov inversion with learned reconstruction. A network far ahead on its training image families fell behind on unseen thin structures, and two preregistered experiments tested why.

Scientific ML · Model reduction

Reduced models & neural operators

Comparing fast approximations of nonlinear transport.

Compared classical and learned PDE surrogates: POD achieved 0.152% relative L² error versus 0.90% for FNO on 40 in-distribution cases (five FNO seeds).

Dynamical systems · Uncertainty

Data assimilation for chaotic Lorenz-96

Estimating chaotic system states from noisy observations.

In a 10-seed study with a selected localisation radius, reduced state-estimation RMSE from 4.63 to 0.41 using Ensemble Kalman filtering.

M.Sc. thesis · Applied mathematics

Optimal mixing of passive scalars

Reproducible pseudo-spectral study of optimal passive-scalar mixing.

Extended M.Sc. thesis computations to N=512 with 48 verification tests; established approximately second-order convergence of fixed-window exponent fits.

CFD · Finite elements

Finite-element cylinder-flow benchmarks

Measuring solver accuracy on standard cylinder-flow problems.

Taylor–Hood finite-element solver verified at O(h³)/O(h²) velocity convergence, with steady cylinder-flow results closely matching the published reference.

Multimodal RAG · Document understanding

Multimodal Visual RAG ↗

Question answering over document pages containing text, tables, charts and images.

Compares OCR-based keyword and dense retrieval with image embeddings, hybrid fusion and reranking; evaluates answer grounding, page citations and abstention. On the documented textbook corpus, text hybrid retrieval was a strong baseline and visual retrieval did not show a meaningful improvement. GPU experiments remain separately pending.

Legal RAG · Citation verification

Legal Research RAG ↗

Source-grounded case-law retrieval and research summaries with citation checks.

Evaluates BM25, dense and hybrid retrieval, reranking, jurisdiction and date constraints, citation support and abstention. On 2,000 test queries, BM25 reached nDCG@10 of 0.176; normalized-score hybrid reached 0.186. Citation existence checks worked reliably, but substantive support and abstention remain limitations.
