🎓 Bouthaina Slika defends her PhD on AI for Pulmonary Disease Assessment!

🎉 Congratulations to Bouthaina Slika on the successful defense of her PhD thesis,
“Advancing Pulmonary Disease Assessment in Medical Imaging: Deep Regression and Data Augmentation Techniques”, on Tuesday, July 22, 2025 (10:30 am) at the University of the Basque Country (UPV/EHU)!

Her thesis was supervised by Dr. Fadi Dornaika and Dr. Karim Hammoudi.


đź§  Thesis Contributions

Bouthaina’s PhD work focuses on developing deep learning models and novel data augmentation methods for accurate and efficient assessment of pulmonary diseases using chest X-rays (CXR) and CT scans. Her research addresses critical challenges in COVID-19, pneumonia, and related pulmonary infections, making strides toward practical, clinically relevant AI systems.

Key contributions include:

  • Multi-Score Prediction of Lung Infection Severity
    A novel multi-task deep learning algorithm combining a dual transformer encoder and feature fusion module. This method simultaneously predicts infection spread and opacity scores, improving accuracy and outperforming state-of-the-art baselines (IEEE TETCI, 2025).

  • Parallel VMamba + Attention Model
    A cutting-edge approach using the VisualStateSpace (VSS) framework and segmented lung replacement augmentation, enabling robust pneumonia severity prediction from CXRs with excellent generalization (Diagnostics, 2025).

  • PViTGAtt-IP Architecture
    A parallel vision transformer model with cross-attention for severity quantification in both CXRs and CT scans, validated across multiple datasets (IEEE Transactions on Big Data, 2025).

  • Lightweight Vision Transformer for CXR Severity
    Developed ViTReg-IP, a transformer-based regressor requiring fewer parameters but maintaining high accuracy and robustness across diverse datasets (MBEC, 2024).

  • Multi-task Vision Transformer (MViTReg-IP)
    Introduced a method for predicting infection extent and opacity simultaneously, improving diagnostic reliability (Conference paper, 2024).

  • SuperpixelGridMasks Augmentation
    Co-developed a new data augmentation technique based on superpixel decomposition, now publicly available on GitHub, showing strong improvements across biomedical and real-world datasets (Journal of Healthcare Informatics Research, 2022).
