研究领域

Our group utilizes molecular, polymeric, and biomacromolecular self-assembly to create ordered arrangement of organic and inorganic functional materials for photonics, opto-electronics, nanomedicine, and nanotechnology. We employ the “molecular engineering” approach to tailor size, shape, sequence, and functionality of organic/hybrid functional materials and explore their applications.
