Profile & Research Interests

As an MR Research Technologist and 9.4T Unit Manager at the CFMM, Dr. Alex Li’s responsibilities are to ensure consistent and stable operation of the 9.4T MRI system, organize projects, and do experiments. In addition, to provide data analysis and on-site help for any users. Dr. Alex Li’s research aims to develop efficient software and novel imaging protocols to acquire high resolution MR images using small animals including mice, rats, birds etc. to monitor the disease progress such as tumour, stroke, alzheimer, etc. Alex Li holds degrees in physics from P.R. China and a Master’s degree in computer science from the University of Western Ontario. He completed his PhD in medical biophysics at the University of Western Ontario under the supervision of Dr. Robert Bartha, with research involving MR Imaging of PARACEST contrast agents in biological systems.
