I am Yiqi Liu (刘逸奇), and I usually go by Andrew. I am a physics Ph.D. student at Princeton University advised by Jo Dunkley. My research focuses on the cosmic microwave background, especially foreground complexity, component separation, and statistical inference for primordial B-mode searches.

Before Princeton, I studied applied mathematics and statistics, physics, and mathematics at Johns Hopkins University, with a minor in computer science. There I worked with Tobias Marriage and Charles Bennett on the CLASS experiment, and with Nadia Zakamska and Hsiang-Chih Hwang on stellar astrophysics.
