| Short Description of the Research Theme |
The research group, comprising Dr. Syed Ali Mardan Azmi, Dr. Rubab Mansoor, Ms. Sana Saleem, Dr. Israr, Dr. Alladita Shahid and graduate students, focuses on foundational and advanced studies in gravitation and spacetime physics. The work centers on the mathematical structure and physical implications of relativistic gravity, emphasizing geometric, symmetry-based, and variational principles that govern spacetime dynamics. The group investigates classical gravitational theory alongside consistent extensions motivated by cosmology, high-energy physics, and quantum considerations. Key themes include the role of symmetry and group structures in relativistic frameworks, the behavior of compact objects and strong-field regimes, and the theoretical description of large-scale cosmic evolution. They also explore generalized gravitational models that modify or extend standard assumptions while maintaining mathematical consistency and observational viability. By combining analytical techniques, geometric methods, and phenomenological analysis, the group aims to deepen understanding of gravity’s fundamental nature and to address open problems related to cosmic acceleration, matter–energy distribution, and the unification of gravitation with fundamental physics. |
