I am interested in quantum gravity and cosmology. My research focuses on the deep role that quantum information plays in these settings. According to the covariant entropy bound, the geometry of spacetime is closely related to its information content. We have sharpened and strengthened this "holographic" relation in recent years. Though strictly a hypothesis about quantum gravity, entropy bounds have become a discovery tool that is yielding new, provable features of relativistic quantum field theory, such as the quantum null energy condition. These and related insights have led to fruitful interactions with quantum information theory and condensed matter physics. They also have useful applications to benchmarking current quantum computing platforms. I lead GeoFlow, a multi-institutional consortium of theorists and experimentalists working at the interface of these areas.

Brief bio: I grew up in southern Germany. (I was born and have family in Israel but never lived there.) When I was little, I thought math was interesting, and I still do. But I decided instead to try to figure out how the universe works. I studied with Stephen Hawking in Cambridge, and I spent postdoc years at Stanford, KITP (Santa Barbara), and Harvard, before joining UC Berkeley as faculty (since 2003).

I am interested in conformal field theory, string theory, and quantum gravity. My research currently focuses on understanding the microscopic details of generalized entropy in quantum gravity using conformal bootstrap techniques.

Newton Cheng

Entanglement measures and their holographic duals. Quantum error correction to understand how bulk degrees of freedom are encoded in boundary degrees of freedom.

Sami Kaya

I am broadly interested in applying concepts from quantum information theory to further our understanding of quantum gravity. Currently I am focusing on understanding various multipartite entanglement measures and studying the role of multi-partite entanglement in spacetime connectivity. I am also interested in studying Quantum Gravity in the Lab type of protocols to understand holographic properties of various CFTs.

Vincent Su

I am interested in understanding how bulk geometry manifests from microscopic degrees of freedom. This includes approaches from quantum error correction and teleportation by size.

Misha Usatyuk

My current interests are in understanding lower dimensional toy models of quantum gravity and how we can use them to better understand the connections between geometry and quantum information. I am also interested in understanding the non-perturbative physics of such models.

Liz Wildenhain

Liz enjoys investigating the apparent paradoxes that appear for evaporating black holes (such as the information paradox and the firewall paradox) and the significance of entanglement wedge islands. She is also broadly interested in applying quantum information concepts to quantum gravity.
