My current work involves 3T imaging, where we are looking at measuring brain-csf-barrier permeability non-invasively in patients with inflammatory bowel disease. We are also finishing a MEG-7T study which looked at patients with focal hand dystonia. Finally, a new project involves activating noci-responsive area 3a, an area of the brain that responds preferentially to painful stimuli.

This work bridges research and clinical imaging, ensuring advanced MRI methods are robust, reproducible, and suitable for real-world deployment in both healthcare. While much of my research has focused on liver and metabolic disease, my expertise extends to MR elastography, spectroscopy, and whole-body MRI, enabling comprehensive, non-invasive assessment of organ health. I am particularly interested in the role of quantitative MRI in health screening and precision imaging for clinical interventions. In addition to my research role, I am an MRI Scanner Operator with responsibility for participant and researcher safety across both Sir Peter Mansfield Imaging Centre sites. I support imaging on Philips 3T, and 7T systems, a GE 3T system, and am working towards competency on Siemens Sola 1.5T scanners. I also train post-doctoral researchers and PhD students in MRI operation and protocol optimisation, ensuring high-quality, reproducible data acquisition while prioritising participant comfort and safety.

Much of my work centres on the design of innovative multi-channel transmit/receive RF coil arrays and the use of artificial electromagnetic materials, including metamaterials and high-permittivity components, to control RF field distributions. I also develop methods for specific absorption rate (SAR) evaluation, B1+ shimming optimisation, and model-based prediction of RF performance. These approaches aim to address longstanding technical challenges in ultra-high-field imaging, such as non-uniform excitation, elevated local SAR, and reduced efficiency of conventional coil architectures.

More recently, my research has expanded to support the development of RF technologies for the 11.7 T whole-body human MRI system. This includes RF coil development, RF safety assessment, coil–scanner interface engineering, and validation frameworks for future parallel-transmission and multi-nuclear imaging. I collaborate widely with academic and industrial partners, with the overarching aim of enabling the next generation of high-performance UHF MRI for neuroscience, clinical research, and biomedical applications.

These projects allow me to apply my previous knowledge in physiology (perinatal health, longterm metabolic health, nutrition) using MRI.

Dr. Kumar earned his PhD at Université Grenoble Alpes, France under the supervision of Dr. Gaël De Paëpe and Dr. Sabine Hediger, where he pioneered DNP methods that provided unprecedented insight into biopolymer structures. He then joined Radboud University Nijmegen in the Netherlands as a postdoctoral researcher with Prof. Arno Kentgens, extending these approaches to synthetic polymers and leading projects on large-scale recycling. He has collaborated with world leading companies such as DSM, Teijin Aramids and KINGFA, and academic groups of leading groups including Prof. Ben Feringa at Univ. Of Groningen, while funded by Dutch Polymer Institute Eindhoven. He has published his work in leading international journals, including Polymer, Chemical Science, and RSC Green Chemistry. At 乐播传媒, Dr. Kumar manages the DNP MAS NMR platform, enabling collaborations across chemistry, physics, and materials science, while continuing his research to push the boundaries of molecular-level characterization for materials of the future.
