Associate Professor
MoSE 3100 N

Dr. Qin is a Professor in the School of Materials Science and Engineering at Georgia Institute of Technology. Her academic records include a B.S. in chemistry from Fudan University, a Ph.D. in physical chemistry from the University of Pennsylvania, a postdoctoral stint in materials science at Harvard University, and an MBA from the University of Washington.

The Qin Lab at GT focuses on the establishment of materials science, chemistry, colloidal science, and surface chemistry for a rational design and controlled synthesis of nanocrystals with desired properties. Specifically, the Lab is actively exploring novel bimetallic nanocrystals with enhanced chemical stability and excellent plasmonic properties sought for a broad range of applications in photonics, electronics, sensing, imaging, catalysis, and biomedicine. Additionally, the Lab is developing methodologies for investigating how the physicochemical characteristics of nanomaterials are correlated with their toxicity in biological systems and ecosystems.
