Matthew Benjamin Kleban is an American theoretical physicist who works on string theory and theoretical cosmology. He is an associate professor at New York University, a member of the Center for Cosmology and Particle Physics, and a former member at the Institute for Advanced Study. His contributions to physics include: The discovery of the first distinct signature of the black hole singularity in AdS/CFT (with Lukasz Fidkowski, Veronika Hubeny and Stephen Shenker) Pioneering work on the subtleties of very late-time cosmology in the presence of a positive cosmological constant, and the "Boltzmann brain" problem (with Lisa Dyson and Leonard Susskind) A determination of the effects of cosmic bubble collisions on the microwave background radiation and other cosmological observables.
