Hi, I am Qiaoya Wu, a third-year graduate student in the Department of Astronomy at the University of Illinois, Urbana-Champaign. I received my Bachelor's degree in Astronomy from Xiamen University in 2021. I work with Prof. Yue Shen on multi-wavelength observations on active galactic nuclei (AGNs/quasars), quasar spectral surveys, and photoionization models. I am also interested in black hole binaries and cosmological large-scale structures.
