Received Ph.D degree from Pondicherry University and pursued postdoctoral fellowship in Raman Research Institute, Bangalore and Indian Institute of Science, Bangalore. My research interest is to study the Optical (steady state and Ultrafast) and Nonlinear Optical properties of materials like Glasss, polymers & Nanomaterials, (Metallic clusters, semiconductors, carbon nanostructures).
We also do corrosion and corrosion inhibition studies on Aerospace and Marine materials through physical, NDT methods.
