Research Summary

The aim of our research is seeing the invisible in 4D. So we are developing ultra-high temporal resolution electron microscopy for recording movies of molecular and atomic motions. Moreover, we are working on generating isolated attosecond electron pulse to attain the attosecond temporal resolution in electron microscopy and establishing the "Attomicroscopy" to image the electron motion in action.
