Jiaru Li

Astronomy & Space Sciences

Summary

I am a Ph.D. student advised by Prof. Dong Lai.

My research interests include exoplanetary dynamics, protoplanetary disks, and the dynamical evolution of embedded black holes in the AGN disks. I primarily study theories in these topics using N-body and hydrodynamics simulations. 

I joined Cornell as a graduate student in 2017. I also spent two years of my grad school at Los Alamos National Laboratory, where I worked with Dr. Hui Li and his group. My bachelor’s degree was obtained at University of Toronto at Scarborough, where I worked with on Prof. Artur Izmaylov on quantum chemistry.

Before I started my university study, I was born and raised in Hangzhou, China.
