Health Informatics & Vision Foundation Models

My current research focuses on trustworthy machine learning and medical-image analysis for healthcare. As a Research Assistant, I contribute to explainable and uncertainty-aware analysis of panoramic radiographs, while my undergraduate thesis evaluates parameter-efficient adaptation of vision foundation models.

Parameter-Efficient Adaptation of Vision Foundation Models for Multi-Class Dental Radiograph Diagnosis

Description

To address the computational costs and representational gaps of applying Vision Foundation Models to dental radiography, this study leverages the DentIRO dataset to analyze embedding-space failure modes. It subsequently benchmarks parameter-efficient fine-tuning methods against full fine-tuning, evaluating model accuracy, robustness, and interpretability under data-scarce conditions.

Objective

This study evaluates frozen Vision Foundation Models (DINOv2, BiomedCLIP, MedSAM) via linear probing to quantify baseline performance gaps on subtle pathologies like caries. It benchmarks parameter-efficient fine-tuning strategies (LoRA, BitFit, VPT) against full fine-tuning while utilizing layer-depth ablations to isolate where localized dental decay features are best learned. Finally, the framework validates model robustness under label-scarce regimes (10–50% data) and confirms clinical alignment using transformer-adapted Grad-CAM heatmaps.

Motivation

Full fine-tuning of Vision Foundation Models on dental radiographs is computationally expensive and constrained by scarce data. This work addresses these domain gaps using parameter-efficient fine-tuning to achieve scalable, accurate, and interpretable dental diagnosis.

Methodological Continuity: From Low-Resource NLP to Clinical AI

My experimental methodology originated in low-resource Natural Language Processing, where lack of standardized benchmarks required building custom corpora, handling dialect variations, and establishing rigorous multi-model evaluation frameworks.

In my current research at the Health Informatics Research Lab and in my undergraduate thesis, I translate these principles to clinical AI—where data scarcity demands parameter-efficient adaptation (LoRA, BitFit, VPT) and diagnostic stakes require rigorous feature attribution (SHAP, Grad-CAM).
