Electron Microscopy Center Director
Limei Cha, Director of the Electron Microscopy Center, graduated from Max Planck Gesellschaft Institute of Metals in Germany, studying under Professor Manfred Ruehle, a famous expert in transmission electron microscopy. She has a profound background in the field of material microstructure and electron microscopy analysis, along with solid theoretical knowledge foundation and rich practical experience. She engaged in material analysis and research for more than ten years in the electron microscope laboratory team of top European countries, such as Germany, Austria, France, etc., and has exchanged and cooperated with top teams at home and abroad. After returning to China, she independently presided over and cooperated in seven national and provincial natural science funds. In the middle of 2018, she joined GTIIT and started to plan and build GTIIT Electron Microscopy Center.
