I am currently looking for a PhD student with a focus on VLMs (Vision-Language Models). If you're interested, please reach out to me!
My principal research area lies at the intersection of computer vision and medical image analysis and machine learning. I specialize in self-supervised learning methods that minimize reliance on extensive labeling, advancing vision-based applications. My work also focuses on improving AI adaptability and generalization through techniques like test-time adaptation and domain generalization, crucial for reliable performance in real-world applications.
I am organizing the EPFL Computer Vision Talks
