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 senior research associate 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 province, which was the capital of the Shang (商) dynasty of ancient China more than 3,000 years ago.

**NEWS** I will be joining the faculty of the Department of Astronomy at Tsinghua University (清华大学) in early 2021.

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

Research

  • Applications of gravitational microlensing.
  • Planet detection and characterization via transit and astrometry method.
  • Connections between planetary and stellar properties.
  • Multi-planet systems: architecture, occurrence rate, stability.
  • Detection and characterization of stellar remnants.

Selected publications:

  • Constraining the oblateness of Kepler planets [ADS]
  • Toward a Galactic distribution of planets. I. Methodology & planet sensitivities of the 2015 high-cadence Spitzer microlens sample [ADS]
  • About 30% of Sun-like stars have Kepler-like planetary systems: a study of their intrinsic architecture [ADS][NAOC Research News (Chinese & English)]
  • The super Earth-cold Jupiter relations [ADS][Brief Intro (in Chinese)][K2SciCon-V slides]
  • On the patterns observed in Kepler multi-planet systems [ADS][EXSS4 slides]

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.
