Peng WangHi, I’m Peng Wang (王鹏), a Professor running  a Sub-atomic Resolution Electron Microscopy Laboratory at Nanjing University (NJU,南京大学), China. My research interests have been in the applications of aberration corrected scanning transmission electron microscopy (STEM) imaging and electron energy loss spectroscopy to characterize functional and energy materials at nano and atomic scales from two to three dimensions.  My current work is focused on advancing a super-resolution coherent diffractive imaging technique, namely Ptychography and also characterizing oxide interfaces and surfaces for energy and information storage materials. I am a member of Institute of Physics (MInstP), Youth Committee of Chinese Materials Research Society (CMRS), Chinese Electron Microscopy Society (CEMS).
