Prof. Tsui’s main research interests include the flow dynamics and surface structure of polymer nanometer films, mechanical and rheological properties of polymer nanostructures and nanocomposites, and impacts of interfaces on these properties. She is also interested in the fundamentals of glass transition, atomic force microscopy, surface analyses, and dielectric spectroscopy.
