Current Research Interests

My general area of research is in the field of magnetic resonance spectroscopy (MRS). I design in vivo techniques for the measurement of metabolites relevant to cancer. My work is conducted with the 3 T and 9.4 T MRI scanners housed at the Cross Cancer Institute. Recently, I have been working on improving proton MRS quantification of lipids. In addition to technical development, I am interested in applying MRS to monitor changes in metabolite levels in response to treatment.
