Professor Li's research interests are studies of solar wind energy coupling into Earth’s magnetosphere and of energetic particle dynamics in the magnetosphere. Current research includes analysis and inter-pretation of particle and field data from satellites and ground stations, energetic particle instru-ment development, modeling and simulation of energetic particle transport associated with mag-netic storms and substorms, and real-time forecast of MeV electrons and the Dst and AE index. Teaching activities include aerospace environment, space dynamics, thermodynamics, and space-flight hardware design. In 2010, he was awarded a CubeSat project from NSF and had been leading a group of graduate students as they design, build, calibrate, and test the CubeSat system, which measured energetic particles in space for more than two years, 2012-2014. Currently he is leading another CubeSat mission (CIRBE), which is scheduled to be launched in April of 2023, and an instrument (MEET: Medium Energy Electron Telescope) development project.
