Research Activities

Greg’s research aims to direct the self-assembly of polymers and use them to synthesize new materials with tailored nano-architectures for optical, chemical, and energy applications. Special focus is given to developing combinatorial, high-throughput, and adaptive experimental methods that will help integrate self-assembly into scalable and cost-effective processes for materials manufacturing.
