Research Interests

Soft condensed matter physics may be foreign to many people. My personal preferred definition is that the bonding energy of the matter is at the order of thermal energy kT. This is a reason why its properties is "soft" instead of "hard" such as metal. Materials of this class include colloids, liquid crystal, membrane, foam, gel, ..and so on. They exist in daily life, for example, paint, salad dressing, cosmetics, ..etc. To put the scope even broader, a biological cell or microscopic biological entitis belong to the subject of study. One of the most fascinating phenomena in this field is self-assembly. In nature we observe many ordered structure which happens on its own. It is important to understand self-assembly and to explore it since this is the key to the bottom-up approach of nanotechnology. Among soft matter physics subjects, I have worked with colloids extensively. They are excellent model systems to investigate statistical mechanics and can be applied to building photonic crystals.

My current research involves two aspects -- tissue engineering scaffold and statistical mechanics in tiny confines. We utilize the self-assembly properties in soft condensed matter to make 3D ordered porous structure for tissue engineering scaffold. The other system is to investigate colloids or polymer in tiny 3D confines.

Job Opportunities

Research positions are available - undergraduate, graduate students, full time/part time research assistant, postdoc, visiting scholars and summer interns. Please contact me and include a CV.
