Our research may be best characterized as biophotonics, photonic materials and molecular engineering. Particular emphasis focuses on the synthesis and characterization of nonlinear optical, photoresponsive, electrostrictive, and magnetostrictive nanostructured materials. Molecular self-assembly and development of new polymer grafting methods are being investigated to prepare stable, highly functionalized polymeric materials.
