Vera2026

FDA 510(k) predicate intelligence platform

An agentic system that finds FDA 510(k) predicate devices in under 30 seconds — work that bills consultants weeks at $400/hr. Built over all 175,013 cleared devices.

LoRA and DPO on GPT-22026

Parameter-efficient fine-tuning study

GPT-2, LoRA, and DPO implemented from scratch. LoRA came within 2.8 points of full fine-tuning using 0.12% of the parameters for classification — and fell apart on generation.

Graph neural networks for network traffic2026

Flow-based device classification

Led the GNN work on a GraphSAGE model over 255,030 device flows, and what a 0.95 weighted F1 hides about rare classes.

Is it the car or the driver?2025

Driver-style embeddings from F1 telemetry

Learning driver-style embeddings from three seasons of F1 qualifying telemetry. Suppress the team signal and driver predictability collapses to chance — the car dominates.

Generating Post-Acetazolamide Cerebral Blood Flow MRI for High-risk Stroke Patients2026

First author · MIDL 2026, Taipei

Image-to-image translation across 194 paired patient scans. A conditional autoencoder outperformed all three diffusion baselines — conditional DDPM, Cold Diffusion, and Residual Diffusion — suggesting the mapping is constrained enough that direct regression beats stochastic generation.
