### Research Interests:

My research in Ph.D focus on the kinetics and dynamics of the phase transitions in block copolymer solutions. We employ the Brownian Dynamics computational simulation to simulate the phase transition as well as small-angle X-ray(SAXS) scattering to study the dynamics of phase transitions by quenching or jumping the temperature quickly. We also built a geometrical model to explain how the HEX cylindrical micelles transform to BCC spherical micelles in block copolymer solutions and performed the Fourier transform of density of the model to compare with the SAXS obtained from experiments.
