Biography

Mitchell Winnik is a University Professor in the Department of Chemistry at the University of Toronto. His current research focuses on polymer material chemistry, specifically crystallization-driven self-assembly (CDSA) of block copolymers and their biomedical applications. His work explores the influence of nanoparticle surface chemistry on cell uptake and penetration into multicellular tumor spheroids, which model avascular tumor regions. He is also developing new reagents for mass cytometry, a high-throughput technique for measuring biomarkers in individual cells using antibodies labeled with heavy metal isotopes. This technology is advancing to measure more than 120 parameters, although progress is limited by the availability of reagents that can bind soft heavy metal ions. His collaborations with Standard BioTools and the coatings industry support the development of environmentally compliant paints and coatings. He utilizes emulsion polymerization to synthesize polymer nanoparticles and studies their complex structures using fluorescence resonance energy transfer techniques. Winnik's approach emphasizes teamwork and brings together students from diverse backgrounds, fostering strong industry collaboration.
