Lan Jian works in the Heliospheric Physics Laboratory (Code 672) at NASA/GSFC. Her research topics include solar and solar wind activities, particle acceleration and wave-particle interaction, solar-terrestrial relation, space weather prediction, outer heliosphere and local interstellar medium. She has worked on the analysis and interpretation of various solar wind structures, from macroscale to microscale. She has done extensive validation for the prediction of solar wind and coronal mass ejections (CMEs) using multiple coronal and heliospheric models. She has processed and calibrated magnetometer data for NASA missions.
