Paul graduated in Electrical Engineering with distinction from the University of Calicut, Kerala, India, in 1987 and received Master’s (1992) and Doctoral degree (2000) in Electrical Engineering from the Indian Institute of Technology, Madras, India. He held Postdoctoral position at the Johns Hopkins University School of Medicine, Baltimore, MD, USA and faculty positions at the National University of Singapore and the University of New South Wales, Sydney, Australia. He is currently a Professor with the Medical Image Computing and Signal Processing Group, Indian Institute of Information Technology and Management-Kerala (IIITM-K), Trivandrum, India. His current interests include compressed sensing, image reconstruction for parallel MRI, and image processing for diagnostic applications.

Our research is mainly focused on the key areas of Parallel Imaging, Compressed Sensing and Image Reconstruction. For details, please refer to www.iiitmk.ac.in/MedImagCompLab/ . For a quick survey, some of the important aspects of the nature of our work are:

  • Exploration of the applications of machine learning and signal processing ideas for conceptual advancements of parallel imaging, compressive sensing and other reconstruction techniques currently used in MR technology within and outside of clinical practice.
  • Exploration of newer, computationally cheaper and user friendly modifications of advanced reconstruction due particularly to the remarkable improvements in image quality and speed evolved directly from technological advances in the construction of high-field superconducting magnets and design improvements in electronics to easily maneuver magnetic field gradients.
  • Input to our research is founded on problems facing clinician scientists at the department of imaging sciences, Sree Chitra Tirunal Institute for Medical Sciences and Technology.
  • Tools for image reconstruction and post-processing are developed in tandem with models and ideas expounded by topical experts at GE Bangalore and overseas.
