In applied and adaptive opitcs, the broad research areas are singular optics (optical vortex), high numerical aperture focusing, speckle, coherence & Stokes holography and polarization imaging.

Application of optical weak measurement and correlation techniques for interferometry, polarimetry and spectroscopy with applications to space-based imaging and development of highly sensitive optical sensors and metrology tools.

Research is also being carried out on several aspects of classical optics such as wavefront analysis, phase estimation, and application of matrix methods in classical optics.

In atomic and molecular physics both experimental and theoretical research is being done. The areas include X-ray emission spectroscopy of highly charged ions, molecular photo absorption spectroscopy, mass spectrometry of molecular ions, bio molecules, cluster ions and giant resonances.

In condensed matter physics, experimental research focuses on topics such as atomic layer deposition, thin film electronics, thin film solar cells, semiconductors, metal nanostructures, self-assembly by molecular beam epitaxy (MBE), study of low dimensional structures by scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS).

Theoretical research is being carried out in quantum many body systems, with particular emphasis on spin systems and topological order. Exactly solvable models such as the Kitaev model and its variants are being studied with a view to understanding the nature of various topological excitations.

Probing interactions of electrons and their elementary excitations close to Fermi level is of fundamental (as well as of practical relevance) interest to understand the electronic properties in strongly correlated electron systems.
We use spectroscopic Imaging Scanning Tunnelling Microscope (SI-STM) to visualize the quantum realm of these electronic structures both in real space(r-space) and momentum space (k-space).
