Alexander Maloney is a theoretical physicist working on problems in quantum field theory and quantum gravity. His primary interests include questions related to the quantum structure of space-time, and in particular the entropy and thermodynamics of black holes. He has made important contributions to the study of conformal field theories, particularly those in two dimensions, and in the interplay between the dynamics of strongly coupled field theories and theories of gravity. He has played an important role in the use of quantum information theoretic methods in quantum field theories and quantum gravity.

Maloney received a B.Sc. in physics and an M.Sc. in mathematics from Stanford University in 1998, and a Ph.D. in physics from Harvard University in 2003. This was followed by postdoctoral positions at the Stanford Linear Accelerator Center and the Institute for Advanced Study in Princeton. He joined the faculty of McGill University in 2007, where he was a James McGill professor and Sir William Macdonald Chair in Physics. In 2024 he moved to Syracuse University, where is the Kathy and Stan Walters Endowed Professor of Quantum Science and director of the Institute for Quantum and Information Sciences.
