Research Summary:

Dr. Qian’s lab focuses on research in both basic and translational sciences. The Qian Lab is developing advanced nonlinear vibrational imaging methods, combining physics/chemistry and machine learning tools, aiming to achieve higher throughput for tissue imaging, and to enable fast, precision cancer diagnosis and prognosis. Dr. Qian developed new imaging methods that enabled scalable label-free super-resolution interrogations of protein-rich biological structures, offering new tools for cancer imaging and brain imaging.

Dr. Qian’s research interests also include single cell metabolite imaging. As part of his postdoctoral fellowship at Caltech, Dr. Qian worked with pioneers in cancer therapy and single cell metabolomics, demonstrated the promise of Raman spectro-microscopy for mapping metabolites in single cells, and discovered new druggable metabolic susceptibilities. The Qian Lab at Sunnybrook is developing the next-generation imaging methods for single cell metabolomics studies.
