Our group's research is mainly based on Inorganic and Metal-Organic materials and their design, especially towards the following broad topics.
Thurst 1: Photo-chemistry and Molecular Actuators
Our group's one of the main research focus is the design of solid-state (both multi-component organic and metal-organic) materials. Among cycloaddition (both [2+2] and [4+4] dimerization) reactions are the main tools which will be explored in our lab.
The application of these photoreactions are mainly explored towards, photosalient effect to convert the light energy into mechanical force (molecular photoactuators).

Thurst 2: Battery Materials, Applications and Their Degradation Mechanism
Metal-ion batteries (Li-ion, Na-ion, and other metal-ion batteries) are a proven energy storage technology in various applications, including automobiles, power plants, etc. However, the life span of these batteries could be improved. Currently, we are trying to understand the reasons behind this limited lifetime and procedures to enhance the lifetime of these batteries through proper analysis of degradation mechanisms and related studies.
Thurst 3: Optical and Nonlinear Optical Applications
The second broad research area of our group is the design of NLO active solid-state materials, especially focused towards multi-photon absorption and lasing applications.
These materials have high potential towards molecular lasers and sensing studies both in real world and defense applications.
Photo-physical and nonlinear optical properties of organic and hybrid materials.
