I'm a postdoctoral researcher focusing on the development of a high-sensitivity MEMS/NEMS-based sensor device for gas and biosensor applications. For device fabrication, I have experience with lithography techniques such as E-beam, mask/mask-less UV, and imprint for solar cell and sensor applications. I have extensive clean room (Class 10,000, 1,000, and 100) expertise with PVD, ICP-CVD/RIE, and lithography-based tools, as well as a strong instrumentation background. My doctoral focused on Advanced Micro-Patterned, Narrow Finger Width Front Contact Metallization Schemes for Silicon Solar Cells. I have extensive experience in the fabrication and characterization of silicon and thin-film solar cells, as well as in-house tool development. I designed and built four pilot scale machines. As an interdisciplinary researcher, I've also worked on the development of chemi-resistive type gas sensor devices based on metal oxides, thin films, and other materials. Defect engineered metal oxides and their surface structural improvements in surface reactive sensing platforms for flexible, temperature-independent, and low-power MEMS gas sensors were the focus of the research.
