Sabrina Gonzalez Pasterski (PhD Harvard University, 2019) is a high energy theorist who joined the Perimeter faculty in 2021 after completing a Postdoctoral Fellowship at the Princeton Centre for Theoretical Science. Her research prior to joining PI includes discovering infinite dimensional symmetry enhancements of the S-matrix, a new observable memory effect in gravity, and a framework for generalizing these features of infrared physics to other theories. As the founder and principal investigator of our new Celestial Holography Initiative, she is leading a team of amplitudes, mathematical physics, and quantum gravity researchers in a concerted effort to tackle the problem of uniting our understanding of spacetime with quantum theory by encoding our universe as a hologram.
