Dr. Fang's research focuses on the interdisciplinary area of physics, chemistry, materials and biology, with an emphasis on self-organized biological systems and self-assembled nanostructural materials. Technology development such as scanning probe microscopy, liquid crystal optical amplification, and soft lithography also plays a major role in his research activities. This area has rich opportunities for students both in fundamental science and practical technologies.

There are four current projects in Dr. Fang's Group:
1. Imaging order, defects and dynamics of biological interfaces with liquid crystals.
2. Stretching polymers and biopolymers in thin films with scanning probe microscope.
3. Nanomaterials based on self-assembly of biological building blocks such as lipids, peptides, DNA and Virus.
4. Protein crystal-directed assembly of 2-D and 3-D inorganic nanocrystals.
