RESEARCH INTERESTS

Development and commercialization of new generation of energy resources is becoming increasingly more important. There is a wide range of nanoscience applications to increase the efficiency and reduce the costs associated with such power generation structures. My current research aims to create cheap solution processable photovoltaic devices that could be mass produced using roll-to-roll techniques. More explicitly, my research focuses on two engineering concepts: 1) Synthesis and characterization of optically active films through solution processable techniques, 2) Fabrication and analysis of optical devices that are produced through such low cost methods.
