Michael Wong

Professor of Chemical and Biomolecular Engineering and Chemistry

My laboratory is engaged in interdisciplinary research at the interface of Chemical Engineering, Chemistry, and Materials Science, with a focus on designing functional nanoparticle-based materials for catalytic and encapsulation/delivery applications. To achieve synthetic control over the materials structures, we seek to develop the chemical tools necessary for nanoparticle assembly to take place, and this requires an intimate understanding of the underlying chemical and colloidal interactions that can dominate at the nanometer scale. Treating nanoparticles as building blocks and assembling them into functional archetypal structures is a powerful concept in materials synthesis and chemical engineering, in which the dimension-dependent properties of the nanoparticles can be handled and exploited in a usable form. Emerging innovations from my laboratory center on several new types of nanostructured materials: (1) nanoparticle-supported metal oxides as next-generation catalysts; (2) hollow microcapsules that can self-assemble from nanoparticles and polymers; and (3) palladium-coated gold nanoparticles that are ~2000 times more active than palladium black for the environmental remediation of water contaminated by chlorinated compounds. We are also learning how to scale up quantum dot synthesis through a combined experimental and computational approach.
