Research

Research Interests

My research centers on controllable synthetic data for data-scarce medical imaging, aiming to make downstream medical AI models more robust when high-quality annotations are limited or expensive.

Medical Synthetic Data

Generating high-fidelity medical images, lesion-like variations, device samples, and training pairs for scarce-data tasks.

Geometry-Constrained Generation

Editing vascular structures with pixel-level boundary control and preservation of non-target anatomy.

Diffusion, OT, and Bridges

Using optimal transport and diffusion Schrodinger bridge formulations for path-level generative control.

Model Evaluation

Assessing model information discrepancy and interpretability through dataset-independent visual signals.
