Ph. D. (University of British Columbia, 2000)

Courses:
(2020-2021)

  • PHYS-2202: Optics & Waves (Winter 2021)

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 also have a general interest in magnetics, including coil design, active and passive shielding, and magnetometry.
