RESEARCH INTERESTS
Daphne's research interests lie in Artificial Intelligence, particularly deep learning applications in biomedicine. Her current work focuses on developing novel computer vision methods for histopathology image analysis, with the goal of extracting valuable insights into cancer and improving model generalization.
PhD research on "VLMs for Medical Imaging"
Abstract: The application and adaptation of recent Large Vision-Language Models (LVLMs) for stroke risk stratification is examined, using carotid ultrasound data from patients with atherosclerosis and specialized prompts. During zero-shot evaluation, 3 out of 6 models recognized the imaging modality and anatomy but provided incorrect risk assessment. Adaptation with additional clinical data significantly improved performance, suggesting potential future clinical use.
