Dr. Ken Yeung's research focuses on biological mass spectrometry and tissue imaging. His laboratory employs matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) to characterize the mass spectral profiles of brain tissues, aiming to map the spatial distribution of important biomolecules relevant to neuroscience. By continuously collecting mass spectra of tissue samples and plotting the intensities of selected masses, he generates detailed MS images that reveal significant changes in the molecular composition of brain regions related to specific signaling pathways and mental health symptoms. In collaboration with the Schulich School of Medicine & Dentistry, Dr. Yeung's team applies MALDI MS imaging techniques to study the distributions of peptides, lipids, and neurotransmitters. Additionally, he works with researchers from Agriculture and Agri-Food Canada to identify mycotoxins and environmental pollutants impacting Canadian agriculture, employing liquid chromatography electrospray ionization mass spectrometry (LC ESI MS) as a primary analytical tool. Ongoing projects also include research on biomass waste conversion into alternative fuels and specialty chemicals at the Institute of Chemicals, Fuels, and Alternative Resources.
