My background is in machine learning and medical image analysis. I focus on weakly-supervised algorithms, such as learning from similarities, or learning from data that is annotated in groups. Currently I am working on such algorithms for classification problems in chest CT and brain MR images, where annotations are scarce.
I recently started a project on crowdsourcing to address this annotation problem. The key idea is that even though crowd workers are not medical experts, they could still provide weak annotations. The current application is annotating airways in chest CT images, but the approach is more general, and my goal is to develop this into my own line of research.
