Research Interest

Highly skilled in nonlinear optical characterization of semiconductor materials using tunable laser system and optical spectroscopic techniques. I have been productively involved in cutting edge research opportunities and in turn contributed immensely in the characterization of nonlinear optical properties of novel materials. My current research interest spans across;

• Computational study of electronic structure properties of novel nonlinear optical materials using Density Functional Theory.
• Nonlinear optical properties of emerging perovskite solar cell materials.
• Nonlinear optical responses of chalcogenides and multiferroic materials in the mid-infrared (IR) frequencies.
