Research

Three themes, one method.

A clinician-defensible model is not one technique — it's a stack: calibration, interpretability, pediatric-specific data, and external validation. Each theme contributes one layer.

Theme · Foundations

Responsible AI for medicine.

We design transformer architectures that are calibrated, robust, and Lipschitz-bounded — so a model's confidence has clinical meaning. LRFormer (UAI 2023) provides a theoretical guarantee for uncertainty estimation in single-forward-pass vision models, addressing the overconfidence that has kept transformers off the wards.

ViTASD pipeline
Theme · Applied

AI for Autism Spectrum Disorder.

ViTASD (ICASSP 2023) introduced a robust ViT baseline for pediatric ASD facial diagnosis — distilling knowledge from large facial-expression datasets and adding a Gaussian-process decoder for clinical robustness.

AggPose multi-scale aggregation
Theme · Open

Open pediatric AI.

We build and release open tools where pediatric medicine has been overlooked. AggPose (IJCAI 2022) is a large-scale infant pose-estimation dataset and a high-resolution transformer model intended to support pediatric research on early neurodevelopmental assessment. Datasets, weights, and training recipes are released under permissive licenses.
