プロフィール概要

My research experiences involve modeling techniques at electronic, atomic, and continuum level. A variety of data analysis techniques was used to extract information from the simulation data. I have applied these techniques to understand the morphology of surfactants at different interfaces, nanotubes in lipid membranes with Dr. Alberto Striolo in the University of Oklahoma. Our research on surfactants interactions with nanotube has enabled us to provide mechanistic details of nanotube dispersion with a variety of surfactants. I have also researched on fluid and nanoparticle transport in porous media with Dr. Dimitrios Papavassiliou at the University of Oklahoma for enhanced oil recovery applications. My current research involves modeling morphology, aggregation, electronic properties, and charge transport in organic molecules for applications involving organic photovoltaics at the Georgia Institute of Technology. My research was instrumental to understand the reasons for the poor strength in active layers of bulk heterojunction (BHJ) films using molecular simulations and also understanding the packing effects of different adducts of fullerene derivatives on charge transport and electron mobility.
