Professor Kachru is widely interested in the foundational theoretical questions underlying cosmology, condensed matter theory, particle theory, and quantum gravity. These include the nature of the initial cosmological singularity; the microscopic theory of inflation; field theory and string theory models of strongly correlated condensed matter systems; and possible solutions of the hierarchy problem (with implications for beyond-the-Standard-Model physics). He also has an abiding interest in the mathematical structure underlying string theory and string compactifications.
