Research Interest

Use the self-consistent field theory (SCFT), time-dependent Ginzburg-Landau theory, and coarse-grained particle simulations to study the self-assembly of block copolymers, including

1. Forward problem of block copolymer self-assembly

explore the formation of possible ordered structures from the self-assembly of various known block copolymers

2. Inverse problem of block copolymer self-assembly

design the molecular architectures of block copolymers for desired structures

3. Directed self-assembly (DSA)

study the structure formation from directed self-assembly of block copolymers by purposely designed guiding patterns, aiming to optimize the guiding patterns for targeted structures
