Experimentalist: Solid State, Condensed Matter 

My research interest is on nanomaterials for renewable energy and I specialize in the synthesis and characterization of these materials for the applications in organic solar cells, Dye sensitized solar cells and perovskite solar cells. My projects involve fabrication of transparent conductive oxides (TCOs) thin films via wet chemistry and surface technologies involving a variety of physical vapor deposition methods.
