Prof. Yeung’s research focus is on the use of Matrix-Assisted Laser Desorption/Ionization mass spectrometry (MALDI MS) for tissue imaging. This technique provides a labeled-free approach to visualize the spatial distribution of the molecules of interest on biological tissue sections.

His research team’s current work focuses on tissue sample treatments that can enhance the sensitivity and selectivity of a variety molecules on brain tissues, including lipids, fatty acids and metabolites. In collaboration with researchers in the Schulich School of Medicine and Dentistry, they study how the brain chemical constituent changes due to various drug influences and neurodegeneration.
