Extensive research description
Dr. Hemant D. Tagare's research interests include 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, and each of the former's foundational issues. Dr. Tagare works on the theoretical and practical problems in bio-medical image analysis. His research focuses on image segmentation, non-rigid registration, 3D reconstruction, and shape theory. Within segmentation, Dr. Tagare mainly studies cardiac ultrasound and brain MRI segmentation, and especially the development of new methodology that draws on machine-learning and advanced numerical optimization techniques. Regarding non-rigid registration, he is developing an axiomatic framework for registration that is applied to brain deformation and atlas building. In 3D reconstruction, Dr. Tagare focuses his research on reconstructing protein structure from Cryogenic Electron Microscopy. In the field of shape theory, his work addresses questions of the topology and geometry of affine shape spaces and non-rigid shape comparison. Dr. Tagare receives research funding from the N.I.H.
