Research Interests

My research focuses on characterizing nanostructure of diffraction-amorphous materials during their crystallization process. The primary tool of my research is the Dynamic Transmission Electron Microscope (DTEM) at LLNL. The DTEM has the unique capability of capturing the evolution of nanomaterial during in-situ experiments with nanosecond temporal resolution. By combining DTEM measurements with other statistical electron microscopy techniques such as Fluctuation Electron Microscopy (FEM), and computer simulations, I try to tackle how various factors, such as composition, thermal history, and deposition methods, affect the kinetics and thermodynamics of the crystallization process.
