Research Overview Our research is oriented to investigation of rheological and dynamic beh aviors of polymer and related materials. Although we basically prefer the oretical approaches, we do experiments to support or apply theoretical investigations. Our research is balanced between purely academic one and practical applications to industries. We study deformation and flow of complex materials including polymer melts, polymer solutions, suspensions, and so on.                                                           Kwang Soo Cho, Kyu Hyun, Kyung Hyun Ahn, and Seung Jong Lee, “A Phenomenological Method for Analysis of Large Amplitude Oscillatory Shear Flow” Proc.
