Overview

Shekhar’s expertise include image processing, discrete tomography and medical image analysis. He received his Ph.D in Theoretical Physics from Monash University, Melbourne in 2010 on a discrete theory of the Radon transform that utilises circulant matrices. He did a post-doctoral fellowship with CSIRO, Brisbane within the biomedical imaging group on musculoskeletal imaging. More specifically, he developed deformable model algorithms for hip and shoulder joint segmentation for deployment on the Siemens Syngo platform. Shekhar’s research will involve developing more image processing and medical image analysis algorithms that will have potential deployment into clinical environments.
