Donald Michael Marolf is a theoretical physicist and professor of physics at the University of California, Santa Barbara.
Marolf gained his Ph.D. from University of Texas at Austin in 1992, under Bryce DeWitt with a thesis on Green's Bracket Algebras and Their Quantization.
[1] His undergraduate degree is from William Jewell College in 1987.
Marolf is an expert on black hole thermodynamics, gravitational aspects in string theory, classical and quantum gravity.
In the past he has worked on the canonical approach to quantum gravity, lower-dimensional models of quantum gravity, issues related to quantization of diffeomorphism-invariant theories, and a number of other topics.
