I am originally from Nepal and did my Master’s degree in Chemistry from Tribhuvan University, Kathmandu, Nepal and PhD from Sun Moon University, South Korea. I am a young, energetic and dedicated materials research scientist having more than 10 years of academic and research experience. My prime research relies on harnessing solar energy by utilizing nanostructured materials for promoting safe environment and green energy technologies with main focus in solar energy harvesting, conversion and storage. As a postdoctoral research work, I have been investigating the most promising quantum dots sensitized TiO2 photoanode architectures for photoelectrochemical (PEC) solar hydrogen generation. My group has developed “giant” core/shell quantum dots sensitized TiO2 photoanodes with enhanced stability and promising efficiency. These novel architectures are very important and pave the way for further research based on quantum dots based photoelectrochemical (PEC) cells to achieve excellent stability and overall PEC cell performance.


 

My research Interest includes the following areas:

• Nanomaterials
• Heterogenous Photocatalysis
• Electrode Materials for Solar PEC water splitting
• Energy storage, harvesting and conversion
• Materials Synthesis and Characterization
• Materials Chemistry and Physics
• Nonlinear Optics ( Upconversion/ downconversion)
