Advisor: Dr. J. Pant (internal) and Dr. K. R. Patil (external)

Thesis: Designing and assembling instruments to synthesize nanoparticulate films using Liquid-Liquid-Interface-Reaction Technique (modified Langmuir-Blodgett) and Solid-Liquid Interface Reaction Technique (modified spin coating).

PhD Project (09/2009-01/2015)

Advisor: Dr. Sheng Yun Wu

Dissertation: Short-range Magnon excitation and spontaneous exchange bias phenomenon in NiO nanoparticles.
