Zachary Fisher is a researcher at Google. As a member of It from Qubit, he was a postdoc at the Perimeter Institute of Theoretical Physics in Waterloo, Ontario. He earned his Ph.D. from the University of California, Berkeley, under the supervision of Raphael Bousso. His work relates to holography and quantum field theory. He is especially interested in discovering novel phenomena in quantum gravity like entropy bounds and exploring quantum field theory as a weak-gravity limit of quantum gravity.
