The department has Ph. D. Programme both in experimental as well as theoretical physics. Students in this Programme are trained through rigorous course work covering basic as well as advanced level courses before starting their research work. The major research areas in the department are Cosmology, High Energy Physics, Material Science, Photovoltaic, Solar Cell, Biosensors and Nanotechnology, Theoretical and computational Biophysics, General relativity, Black holes, Quantum Gravity and Theoretical Condensed Matter Physics.
