Welcome to Wei's Homepage

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

-Albert Einstein-

My name is Wei Zhu (祝伟). I'm now a post-doctoral fellow 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 in China in 2013. I grew up in An Yang (安阳) of Henan 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. Also feel free to contact me: weizhu (at) cita.utoronto.ca


  • Applications of gravitational microlensing in exoplanets, stellar binaries and isolated objects.
  • Joint analysis of ground-based and space-based (Spitzer, K2, WFIRST) microlensing observations [see here].

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 super strong rock climber.
