研究领域

Inorganic Chemistry

The primary research activities in my group focus on (1) the design, synthesis, and self-assembly of novel inorganic nanomaterials and organic-inorganic hybrid nanostructured and nanoporous materials and nanobiomaterials; (2) catalysis and nanocatalysis; (3) nanomaterials for biological, medical, and biosensing applications; and (4) nanomaterials for solar cell applications. Our nanomaterials are typically chosen to have multifunctional groups as well as novel structures and shapes at the nanometer scale. Uncovering the structure-property relationships as well as the potential applications of these materials for catalysis, nanoelectronics, separations, sensing, biosensing and drug delivery is also part of our research program.
