👋 Welcome to Yilun’s Personal Website!

Hi there! My name is Yilun Guan, a Cosmologist at the Dunlap Institute of Astrophysics and Astronomy in the University of Toronto. On a random day I’m either thinking about cool science to do with the Cosmic Microwave Background measurements, or building software for the next-generation CMB telescope, the Simons Observatory, or having fun with emacs!
