Tsui, Ophelia K. C. - Boston University - Department of Materials Science & Engineering

研究领域

My research interests encompass several areas of soft condensed matter physics, including the dynamics of polymer nanometer films and nanocomposites, dewetting instability of polymer thin films, wetting properties of textured surfaces, and control of particle trajectories in microfluidics. As atomic force microscopy (AFM) is a major tool in my research, I am also engaged in the development and application of various AFM techniques such as AFM mechanics, nanotribology and nanolithography.
