Research Interests:

My main research interest is the development of novel techniques of nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI), with a particular focus on low field NMR/MRI and the use of hyperpolarized nuclei.  Applications of my work range from medical imaging to fundamental physics.  Current research projects and collaborations include (i) TRASE MRI, which is a new imaging technique that uses RF phase-gradient fields to achieve spatial encoding, (ii) experimental searches of the possible permanent electric dipole moment (EDM) of the neutron and Xe-129, and (iii) high performance computing using graphics processing units (GPUs).  I have a general interest in magnetics, including coil design, active and passive shielding, and magnetometry.

I am also co-founder of the TerraByte project (https://acs.uwinnipeg.ca/terrabyte/) at UWinnipeg with Dr. Christopher Henry.  A primary goal of this work is to enable the development of machine learning applications in agriculture through the automated generation of labled images of Canadian crop plants and weeds. The data sets will be made publicly available in order to spur innovation.
