- Exploring the aspects of Semiclassical Gravity Theory in the context of the black hole and cosmological spacetime.
- Studying the applications of the Unruh-Fulling effect, (which plays a crucial role in understanding the Quantum Field Theory in curved spacetime/semiclassical gravity theory) via the Unruh-deWitt detector method in flat/curved spacetime.
- The relativistic Quantum information theory (RQI), where one studies quantum information theory in the background of flat/curved spacetime.
- Studying the phenomena of quantum entanglement and its consequences, such as entanglement harvesting in flat and curved spacetime.
- Exploring the phenomenological implications of the theories with minimal length scale such as the Generalised Uncertainty Principle (GUP), Relativistic version of GUP, etc.
