Tien-Tien Yu, Department of Physics

Academic Areas:
Dark Matter, Cosmology

Tien-Tien Yu is an academic expert in dark matter and cosmology. At the University of Oregon, she is an assistant professor in the Department of Physics and the Institute for Theoretical Science. Dr. Yu is a theoretical particle physicist working at the interface of theory and experiment. She is particularly interested in understanding the nature of dark matter, whose existence is known through its gravitational effects on ordinary matter. Dr. Yu has studied the nature of dark matter through a variety of different methods, ranging from using collider and accelerator probes at CERN, home of the Large Hadron Collider, to produce dark matter, to observing signatures of dark matter in astrophysical and cosmological observations. Most recently, she has co-founded the SENSEI collaboration, which is an experiment utilizing silicon chips, much like those found in digital cameras, to search for dark matter passing through the Earth.

Prior to arriving in Eugene, she was a fellow in the theoretical physics group at CERN in Geneva, Switzerland, and a post-doctoral associate at the Yang Institute for Theoretical Physics at Stony Brook University in NY.
