About
Rosalie Chu is a leading figure in the development of cutting-edge mass spectrometry imaging (MSI) and spatial proteomics technologies. Her research focuses on pushing the boundaries of spatial resolution and sensitivity for mapping biomolecules directly from tissue and microbial samples. Chu’s major contribution is the creation of an integrated, automated method for spatially resolved proteome mapping, which combines laser capture microdissection with automated sample transfer to nanodroplets. This groundbreaking workflow, detailed in her highly cited 2018 paper (141 citations), overcomes the sensitivity limitations of conventional proteomics, enabling the detailed mapping of protein expression in tissue sections at unprecedented spatial resolution. Additionally, her work on utilizing a robotic sprayer for high lateral and mass resolution MALDI FT-ICR MSI of microbial cultures (33 citations) has provided a powerful tool for visualizing biochemical interactions within microbial communities, replacing uneven manual matrix application with a reliable automated system. Through these innovations, Chu has established herself as a key innovator in spatial biology, providing the research community with robust tools to explore the molecular architecture of complex biological systems.
