I worked as a research consultant in GE GRC (Shanghai). My main task was to establish a data analysis based controller design strategy for DFIG wind generators. I built the basic structure of the method and proposed a detailed solution strategy.

I served as an oral English instructor in New Oriental Corporation, Guiyang. I helped more than 50 students to practice their oral English. I also evaluated the oral English standard of more than 20 new entrants to recommend the appropriate course for them.
