How can we use quantum field theory and string theory to understand key questions in high energy theory, cosmology, and condensed matter physics? Do the hints of deep mathematical structures underlying string theory contain new lessons for fundamental physics?

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.

Current areas of focus:

- Finding mathematically precise criteria for the emergence of weakly curved space-time geometry from dual quantum field theories (through constraints on observables like the elliptic genus)
- Mysterious relations between modular forms, string compactifications, and sporadic simple groups (``Moonshine")
- Application of techniques of modern quantum field theory to develop a controlled understanding of novel phases of condensed matter systems
