• Designed, programmed (Python), and tested in-situ thin-film deposition/coating tool combined with small angle X-ray scattering (GISAXS, GIWAXS) and ellipsometry.
• Extensive hands-on experience working in a wet lab and cleanroom related to thin film semiconductor and compound semiconductor materials, thin film deposition, testing, characterization, performance metrics.
• Investigated fundamental relationships between low-k dielectric thin films, process parameters (dry plasma etching, metal oxide infiltration with ALD) and morphology.
• Analyzed and brainstorm with other group members about how the material properties and processing impact material and device functional performance.
• Optimized and developed process parameters and recipes (plasma etch, gas composition) for low-k dielectric films.
• Performed process characterization, integration and equipment troubleshooting.

Livermore, California, United States

• Assisted e-beam evaporation of Al2O3/Mo/Fe as catalyst for fabrication and plasma etched (RIE) carbon/boron nitride nanotube arrays in cleanroom setting for sensor applications, improved the gas sensing with optimized.
• Executed analytical characterizations of van der Waals nanotubes with Raman spectroscopy, IR, FTIR-ATR, and electron microscopy (SEM/TEM), gathered and organized scientific data analysis, and communicated the results.
• Developed user proposals for characterization tools, created white papers and published results in ACS Nano.
• Led projects focused on developing dry etch techniques (ULVAC systems) for high aspect ratio structures for carbon surfaces, Si, and SiO2.

Piscataway, New Jersey, United States

• Developed a novel, solution-based fabrication method for nanotube powder-embedded photocurable polymer thin-films (amorphous and crystalline).(Highlighted news in Science magazine, December 4th, 2019, Sponsored by NSF.
• Utilized a variety of material/surface chemistry characterization and electrochemical sensing techniques, developed photo-curable polymer formulations, hand-on characterization experience with scanning and transmission.
• Pioneered rheology characterization of powders (nanotube powder flow, agglomeration, segregation, stickiness).
• Executed particle size analysis (DLS) and rheology characterization of inorganic/polymer suspensions (miscibility, molecular diffusion and physical instability), analyzed routes to prevent agglomeration in polymer.
• Led theoretical and experimental analysis of fundamental ion transport phenomena and structural relationships, and material surface charge effects for Li-ion cell separators.
• Developed novel fiber/nanotube/polyurethane-based thin film composites and micro/nanochannel arrays for energy generation and storage applications, resulting in five journal publications, a patent, and an NSF grant.
