## Jia Liu

Welcome to my research website! I am an NSF postdoctoral fellow in the Department of Astrophysical Sciences at Princeton University.

My current work focuses on weak lensing non-Gaussian statistics, using N-body ray tracing simulations as a tool to study the large scale structure of our universe. The ultimate goal of this work is to understand the nature of dark energy, the total mass of neutrinos, and other cosmological parameters.

I also spend a small amount of my time observing AGNs at optical telescopes, hoping to find supermassive black hole binaries!

Recently, I wrote an article about my experience transiting from a business major to an astrophysicist/cosmologist.
