Dr. Weijie Sun is an assistant research physicist at the Space Sciences Laboratory at the University of California at Berkeley. Prior to joining SSL, he held positions as a postdoctoral research fellow and later an assistant research scientist at the Department of Climate and Space Sciences and Engineering at the University of Michigan, Ann Arbor. Dr. Sun earned his Ph.D. degree from Peking University in 2016, supported by the Peking University President’s Scholarship.

His research interests include topics such as magnetic reconnection, particle energization, and comparative planetary magnetospheres. Dr. Sun has authored and co-authored over 100 publications, some of which have been featured in Eos, the news magazine published by the American Geophysical Union. For example, his work of a study on Flux Transfer Event Showers influencing solar wind precipitation and planetary ion outflow at Mercury [Sun et al., 2022a]. He has also contributed to an invited review on the dynamic of Mercury’s magnetosphere and compare with Earth’s magnetosphere [Sun et al., 2022b].

Dr. Sun has been serving in the Scientist-In-The-Loop (SITL) of the NASA Magnetospheric Multiscale (MMS) mission since 2018. He serves as a Co-Investigator for the Mercury Plasma/Particle Experiment (MPPE) of Mercury Magnetosphere Orbiter (Mio) on the ESA-JAXA BepiColombo Mission. He has been actively involved in BepiColombo’s Young Scientist Groups.

Dr. Sun actively contributes to the scientific community. He serves on review panels for both Heliosphysics and Planetary divisions at NASA ROSES, the National Science Foundation (NSF), and several European Research Foundations. Additionally, he is a frequent reviewer for scientific journals, including Geophysical Research Letters (GRL), Journal of Geophysical Research: Space Physics (JGR-Space Physics), Physical Review Letters (PRL), The Astrophysical Journal (ApJ) and The Astrophysical Journal Letter (ApJL), etc.

Dr. Sun has been invited to present his research at many universities, institutions, and international scientific meetings. Currently, he co-advises two Ph.D. students and mentors several motivated undergraduate students at the University of California, Berkeley.
