I am a Ph.D. candidate at the School of Astronomy and Space Science, Nanjing University, and expect to receive my degree in June 2027. I am currently a visiting Ph.D. student at Leiden Observatory until October 2026.
My current research focuses on two main topics: (a) measuring CNO isotopic ratios in the Milky Way, especially in the Galactic outer disk; and (b) oxygen-bearing chemistry in photodissociation regions (PDRs) with varying C/N/O elemental abundance ratios. I am also interested in the hyperfine anomalies of CN, as well as the excitation and non-LTE radiative transfer of molecular line transitions in molecular clouds and star-forming regions. More details are on the publications and projects pages.
Beyond astronomy, I am also interested in geography, biology, and psychology. I also enjoy mobile photography, science fiction (favorite books: Hyperion Cantos, Remembrance of Earth’s Past and Summa Technologiae), and rock music (favorite band: Dire Straits).
My main collaborators are Zhi-Yu Zhang(Supervisor, see our group webpage), Serena Viti(Supervisor), Jun-Zhi Wang(Co-supervisor), and Thomas G. Bisbas(Co-supervisor)
