PAST RESEARCH PROJECTS

  • Developed a structured low-rank recovery algorithm to accelerate and denoise multi-dimensional spectroscopic data. It was applied to two-dimensional infra-red spectroscopic data and attained a acceleration factor of 8, being the first ever method to retain lineshape information at such high acceleration. It was also applied to in-vivo COSY and J-resolved spectroscopy at 7T.
  • Designed a ultra-high resolution variable density spiral MR sequence for collection of spectroscopic data in just 7.2 minutes. Developed a low-rank constraint based algorithm with orthogonality priors applicable to cartesian and non-cartesian data, for reconstruction of spectroscopic imaging data without using any lipid suppression.
