"The most incomprehensible thing about the universe is that it is comprehensive."

-Albert Einstein-

My name is Wei Zhu (祝伟). I'm an Assistant Professor in the Department of Astronomy at Tsinghua University (清华大学). Previously I was a postdoctoral fellow (09/2017-08/2019) and senior research associate (09/2019-02/2021) at the Canadian Institute for Theoretical Astrophysics. I got my PhD degree from The Ohio State University in the United States in 2017 and a BS degree from Peking University (北京大学) in China in 2013. I grew up in An Yang (安阳) of Henan (河南) province, which was the capital of the Shang (商) dynasty of ancient China more than 3,000 years ago.

My research interests include both theoretical and observational aspects of astrophysics, with a focus on exoplanets.  Please explore this site to find more about my work. I'm looking for motivated (graduate/undergraduate) students to join my group. If you are interested, please feel free to contact me: weizhu (at) mail.tsinghua.edu.cn

Outdoor Activities

I like various kinds of outdoor sports, such as rock climbing (incl. bouldering), skiing, hiking, camping, etc. Rock climbing is currently my favorite sport, even though I'm not a strong rock climber.
