My research interests span: Statistics on Manifolds, Medical Image Computing, Computer Vision and Graphics, Statistical Learning, Information Geometry and Applied Mathematics. Most of my research these days is concerned with efficient recursive computation of statistics on Riemannian manifolds with applications to atlas (reference template) construction, clustering, data retrieval in Medical Imaging and Computer VIsion and Machine Learning. Further, I have also been developing dynamical systems on matrix manifolds e.g., manifold of symmetric positive definite matrices for real-time tracking applications in Computer Vision. Another interesting problem I have performed extensive research on is mapping out the neuronal fiber tracks from diffusion MR scans of human and vertebrate brains. I have been involved in developing algorithms and software for the past 15+ years in the field of diffusion MRI analysis with applications to neurodegenerative disorders such as, Epilepsy, Parkinsons, Alzheimers diseases. In Computer Vision, me and my collaborators have developed state-of-the-art face recognition and face relighting algorithms. My earlier work (in the 90’s) was focused on level-set segmentation methods, and my collaborators (Ravi Malladi and James Sethian) and I introduced the geometric active contours in a level-set framework to the field of Computer Vision (SPIE’93, ECCV’94, PAMI’95). Me and my students developed fast preconditioned Conjugate Gradient Algorithms for a suite of problems in Computer Vision e.g. surface reconstruction with discontinuities from sparse range data sets, shape from shading, optical flow etc. For more details, I invite you to visit my homepage.
