Brief Bio
Lan Jian works in the Heliospheric Physics Laboratory (Code 672) at NASA/GSFC. She has been the Deputy Project Scientist (DPS) of the Space Physics Data Facility (SPDF) since mid 2019. She is the DPS of the Solar Terrestrial Relations Observatory (STEREO) mission, the Deputy PI of Voyager magnetometer team, and a Co-Investigator of the HelioSwarm mission.
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.
Lan Jian has published more than 170 papers (most listed at ORCID: 0000-0002-6849-5527, Web of Science Research ID: B-4053-2010, and Google Scholar), 23 as the first author. She has given nearly 200 first-authored presentations in national and international conferences, including more than 40 invited talks. She has given more than 30 seminars or colloquia at multiple universities and institutes. She has mentored five summer interns, one graduate student, and three postdocs at GSFC.
