Research Interests

I am interested in foundational issues as well as new and innovative approaches to bio-medical image analysis, especially in Cryogenic electron microscopy of proteins, MRI and ultrasound image segmentation, non-rigid registration, shape spaces, and image indexing.

I work on theoretical and practical problems in bio-medical image analysis. My research focuses on image segmentation, non-rigid registration, 3D reconstruction, and shape theory. In segmentation, my research focuses on cardiac ultrasound and brain MRI segmentation, especially on the development of new methodology that draws on machine-learning and advanced numerical optimization techniques. In non-rigid registration, I am developing an axiomatic framework for registration that is applied to brain deformation and atlas building. In 3D reconstruction, my research focuses on reconstructing protein structure from Cryogenic Electron Microscopy. In shape theory, my work addresses questions of the topology and geometry of affine shape spaces and non-rigid shape comparison. My research is funded by the N.I.H.
