Research Interest
Ultrafast Electron Microscopy is a pivotal tool for imaging the atomic motion in real time and space. The temporal resolution, limited to a few hundreds of femtoseconds (one quadrillionth of a second) permits recording movies of only the relatively massive atomic motion. Imaging of microscopic motions outside the atomic nucleus in the real-time requires a significant enhancement in the temporal resolution. My research program aims to obtain the attosecond (one quintillionth of a second) temporal resolution in electron microscopy and establish the “Attomicroscopy” —the fastest camera ever known—which takes the field of ultrafast imaging to the next level. Attomicroscopy provides a real-time access to all microscopic motions outside the atomic core and radically change our insight into the workings of the microcosm. We will use the Attomicroscopy to image the electron motion in biochemical molecules such as amino acids, DNA, protein…. etc. Attosecond imaging and controlling of the electron motion at the atomic scale will open exciting new ground and prospects in multiple fields of basic science, biological applications, and information technology.
