Jiang Ji’an, born in September 1990 in Hefei City, Anhui Province, graduated from the College of Physical Science and Technology of the Central China Normal University in 2013 (2009 Base Class of Physics), obtaining a bachelor's degree. He received his master's and doctoral degrees in astronomy from the University of Tokyo, Japan in March 2016 and March 2019, respectively. During his doctoral study, he served as a JSPS Fellow. From April 2019 to March 2022, he conducted postdoctoral research at the Kavli Institute for the Physics and Mathematics of the Universe of the University of Tokyo. From April 2022 to April 2023, he was a specially appointed researcher at the National Astronomical Observatory of Japan. During his overseas study and work, he independently led several research projects funded by the Japan Society for the Promotion of Science. Since April 2023, he has been a specially appointed professor at the Department of Astronomy of the University of Science and Technology of China and a visiting research fellow at the National Astronomical Observatory of Japan.
His research focuses on various types of extragalactic transients, primarily conducting systematic studies on extragalactic transients through large-field optical/infrared telescope time-domain surveys and multi-wavelength follow-up observations. His research interests include supernovae, progenitors, and explosion mechanisms of various fast transients, discovery of new types of transients, supernova cosmology, and multi-messenger astronomy. In 2014, he established and led the MUSSES project, an early-stage supernova survey using the 8.2-meter Subaru Telescope's Hyper Suprime-Cam (HSC). He is also a core member of the HSC SSP time-domain survey and the Tomo-e Gozen time-domain survey at the University of Tokyo, conducting research on supernovae and other transients. Since 2021, he has led the China-Japan collaborative project on optical counterparts of fast radio bursts. Since 2014, as a Principal Investigator (P.I.), he has accumulated over 1,600 hours of ground-based (including approximately 300 hours on 8-meter-class optical/infrared telescopes) and space telescope observation time. As of April 2023, he has published over 20 SCI papers, including two in Nature (one as first author and sole corresponding author, and one as a co-author), with over 500 citations in total. He has long served as a reviewer for top international journals such as Nature, Nature Astronomy, and the Astrophysical Journal. He is currently a long-term contributing member of the HSC SSP project, a formal member of the Einstein Probe scientific team, and a formal member of the WFST scientific working group, maintaining close collaborations with various international time-domain observation projects.
