Hello, 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.

I got my bachelor degree from the University of Science and Technology of China (USTC) and joined the Johns Hopkins University (JHU) for my Ph.D. study. After graduating from JHU, I spent three years at the University of Pennsylvania for a postdoctoral position. Now I am a postdoctoral associate at the Massachusetts Institute of Technology (MIT).
