Understanding the thermodynamic structure of horizons in different gravity theories.
Towards the understanding of the microscopic description of the horizon thermodynamics through different diffeomorphism symmetries of spacetime.
Studying the phase transition of black holes by treating black hole as a thermal object.
Quantum field theory on curved spacetimes and possible connections with thermal field theory.
Exploring the duality between fluid and gravity and how far fluid equations can be described by gravitational equations.
Particle production in different spacetimes and understating the nature of the dynamics of these particles in the context of nonequilibrium statistical mechanics (mainly fluctuation-dissipation theorem).
Classical and quantum nature of the particle motion very near to the horizon. It may provide the mechanism for generation of horizon temperature.
