My main focus is on the fundamental laws of nature with a special emphasis on gravity. This means I think about General Relativity and Quantum Field Theories a lot. I try my best to keep up with many ongoing experiments in Astrophysics, Cosmology, and High Energy Physics. I often read papers from Mathematics, Condensed Matter Physics, and Atomic, Molecular and Optics. Currently, I am interested in the following topics.
Singularities, black holes, and gravitational collapse
Black hole entropy and Hawking radiation
Scattering amplitudes in gravity and gauge theories
Non-perturbative approach to quantum field theory
Fundamental symmetries of nature and their interconnection
Very early universe, trans-Planckian cosmology, and inflation
Heat kernel techniques in general relativity, quantum field theory, and quantum gravity
My papers can be read at INSPIRE-HEP and Google Scholar.
