My research focuses on the applications of polymeric materials for the following:

(I)                 dispersion and large area patterning of carbon nanotubes for Field Effect Transistors

We have developed various parallel soft-lithography-based patterning techniques to make long (~10μm) but narrow (100nm) patterns of SWNTs. We have also developed several surfactants that can effectively disperse or separate out the metallic nanotubes from the semiconducting tubes.

(II)              Carbon nanotube composites

We have developed a novel reactive fiber spinning technique to spin micro-scale fibers of thermosetting resins (such as cyanate ester or epoxy) with aligned CNT reinforcements to yield composites with improved mechanical properties.

(III)         tissue engineering of small diameter v ascular grafts

We have developed a novel micropatterned biodegradable scaffold for alignment and phenotype of vascular smooth muscle cells and their precursors. We are interested in phenotype regulation by physical topology, growth factors, ECM matrix and stress and the interplay of these.

(IV)           anti-microbial hydrogel materials

We developed UV curable hydrogel for easy coating of biomedical devices to decrease microbial adhesion and growth.
