Research Interests


  • Static and dynamic properties of complex fluids, e.g. biological macromolecules (DNA, protein), polyelectrolytes, block copolymers, and polymer brushes in bulk or under confinements.

  • Numerical algorithms for polymer self-consistent field theory, molecular dynamics simulation, Monte Carlo simulation, and phase field simulation.

  • Thin and ultrathin film polymer crystallization.

Research Experience


Lecturer, 2012 - present Fudan University, Department of Macromolecular Science

  • Chebyshev based self-consistent field theory (SCFT) studies of polymer brushes and polymers under confinements, focusing on the effect of surface affinity. The Chebyshev based SCFT algorithm is highly efficient on non-periodic boundary condition problems.

  • Development of the polyorder project: a unified computing framework for conducting polymer SCFT calculations.

Visiting Researcher, 2014 - 2016 University of California, Santa Barbara, Materials Research Laboratory

  • Field-theoretic simulations of polymeric materials.

  • Developing a density functional model for polymeric systems.

Postdoctoral Research Fellow, 2009 - 2012 Fudan University, Department of Macromolecular Science

  • Developed high performance SCFT methods for studying the equilibrium phase separation structures of block copolymers and polyelectrolytes.

  • Developed multigrid algorithms for solving Poisson-Boltzmann equations.

  • Performed Monte Carlo simulations on the nucleation and growth process in thickening of monolayer PEO crystals in ultrathin films.

Ph.D. Candidate, 2004 - 2009 Peking University, College of Chemistry and Molecular Engineering

  • Introduced the phase field simulation techniques to study morphological evolution of monolayer poly(ethylene oxide) (PEO) crystals.

  • Conducted experimental studies on the nucleation, growth, and thickening of monolayer PEO crystals in ultrathin films using real-time atomic force microsocpy (AFM).

Undergraduate Student, 2003 - 2004 Nanjing University, School of Chemistry and Chemical Engineering

  • Synthesized three amphiphilic ligands and their complexes with Cu^2+.

  • Computed surface properties of supported catalysts using Gaussian 98.
