LUAN Xiaoli, got her PhD. from Wuhan Institute of Physics and Mathematics, the Chinese Academy of Sciences in 2005. She visited High-Altitude Observatory of NCAR in US and then worked there for 5 years. She entered USTC in 2011．Her research interests include simulation on ionized stratum and thermosphere，high latitude auroral activity research and modeling, space weather time process and the ionosphere thermal layer effect, the ionosphere and the magnetosphere coupling mechanism research,etc. Herwork at the high-altitude Observatory focused on the ionosphere hot layer of seasonal change of relevant parameters and its global distribution, with comparison to NCAR TIEGCM.
