Hello! I am Tianji Zhou, and I also go by Jimmy. I am an incoming Physics Ph.D. student at the University of Southern California. I completed my undergraduate studies in Physics and Astronomy at Haverford College, graduating magna cum laude.

My research interests are in data-driven cosmology. I am especially interested in using cosmological observations to test whether tensions in the standard cosmological model point to measurement systematics, modeling choices, or new physics. I have also recently become excited about applying deep learning to problems in cosmology.

My recent work includes model-independent probes of dark sector physics, data-driven approaches to the Hubble tension, and spectral representations of neutron-star equations of state. You can find my papers on the publications page and a structured version of my CV on the CV page.
