• Time-resolved Scanning Electron Microscopy (08/2009–present)
  The newly developed technique is capable of real-space surface imaging of photoinduced dynamical processes in condensed matter and at interfaces under different vacuum conditions. I incorporated an ultrashort time scale into scanning electron microscopy and discovered the two regimes of dynamical probing possible. I observed solvation dynamics by adsorbate molecules at interfaces.
  
  
• Electronic and Structural Dynamics in Condensed Matter and at Interface (04/2004–present)
  I applied the technique of time-resolved electron diffraction to the studies of photoinduced electronic and structural dynamics of materials, interfacial water assemblies, and self-assembled monolayers. I demonstrated the principles that govern the experimental observables and the physical processes at work. Further applications included the investigation of strongly correlated materials such as high-Tc superconductors and those exhibiting phase transitions, structurally intriguing solids such as graphite and perovskite structures, and nanometer-scale materials.
  
  
• Ground-state Dynamics and Mesoscopic Solvation in Gas Phase
  (04/2003–07/2004)
  We applied the time-resolved photoelectron spectroscopy and negative-ion-beam techniques to the studies of the dynamics of solvated electron in size-selected water clusters and the ground-state dynamics (ring-inversion motion) of cyclooctatetraene. I conducted the theoretical calculations and constructed the framework to explain the experimental observation of cyclooctatetraene.
  
  
• Theoretical Investigation of Carbon Nanotubes and 1-D Metal Chains
  (05/2001–08/2002)
  I investigated the formation mechanism, stability, and mechanical property of an experimentally observed triple-stranded carbon nanorope. I also conducted tight-binding calculations for one- dimensional chains of different transition metal ions.
  
  
• Theory of Photoinduced Charge Transfer in Doped Conjugated Polymer
  (09/1997–06/1999)
  I developed a microscopic theory with consideration of lattice relaxation for the system of molecularly doped conjugated polymers. I explored the various factors that may affect the charge transfer rate between a molecular dopant and a conjugated polymer.
