Research interests

To explore the world, people use their eyes and hands to see and to manipulate the objects around them. To see the nano-world and ultrafast electron dynamics, the development of new tools is highly desired. Currently, I focus my research on ultrafast laser technology, and table-top X-ray light source based on high harmonic generation. Because X-ray has very short wavelength, it can easily penetrate thick samples and sense small features. Furthermore, due to lots of element absorption edges between EUV and soft X-ray regime of the spectrum, X-ray can easily sense chemical elements and figure out their states. Huge progresses have been done in recent years during my research in JILA and NTHU. This new accessible and reliable attosecond light source makes it possible to capture the attosecond motion of electrons in a broader range of atoms, molecules, liquids, and materials.
