Yubo's Website

Hey! I'm Yubo, and I'm currently a postdoctoral research fellow at the Canadian Institute for Theoretical Astrophysics (CITA). I was previously a Lyman Spitzer Jr. Postdoctoral Fellow at Princeton University. I obtained my PhD at Cornell University where I was advised by Dong Lai, where I was supported by the NASA Future Investigators in Earth and Space Science and Technology (FINESST) award.
