Welome to my website! I am Zhilei Xu (sound Link to pronounce my name).

I am an astrophysicist interested in studying the beginning and the evolution of the Universe, especially through observing the 21-cm signal and cosmic microwave background (CMB). In addition, I am also interested in the formation and evolution of galaxies and galaxy clusters. I am a member of the HERA collaboration in 21-cm and CLASS, SO, ACT, CMB-S4 collaborations in CMB.
