Kai He joined the Electron Microscopy Group in the Center for Functional Nanomaterials at Brookhaven National Laboratory in July 2013. His research interests include transmission electron microscopy, eletron holography and in-situ applications of nanostructured magnetic, electronic, and energy materials. At CFN, he will be focusing on the application of scanning transmission electron microscopy and in-situ TEM on multiferroics and energy storage materials.
