## About

Liam McAllister is a professor at Cornell University. He received his Ph.D from Stanford University in 2005. He is interested in using string theory to understand the early universe, and in developing compactifications of string theory that lead to realistic four-dimensional physics. Examples of his work include explicit models of D-brane inflation; applications of the AdS/CFT correspondence to determining the structure of D-brane inflation models; a model of large-field inflation based on axion shift symmetries and axion monodromy; signatures of axion monodromy inflation in the CMB spectrum and bispectrum; D-brane probes of nonperturbative effects in flux compactifications; scenarios for sequestering in string compactifications; a set of analytic techniques for generating local solutions of supergravity; explorations of inflation in high-dimensional field spaces; and characterization of the dynamics of relativistic D-branes. Liam is a member of the Modern Inflationary Cosmology research team led by SITP faculty member Eva Silverstein.
