I am a materials scientist with more than 10 years of hands-on research experience specializing in nanoscale fabrication and characterization, including thin film coating and nanoparticle synthesis. I study the surface chemistry, optical properties, and crystal structure of the materials using SEM, EDS, XRD, UV-Vis, etc. I have taken more than 2,500 SEM images (300+ hrs). I am a fast learner and can take all materials science & chemical engineering related field (organic, inorganic, ceramic, metal, semiconductor, polymer, bio) immediately. I am looking for a full time Materials Scientist/Chemist/R&D/Engineer position including, but not limited to: wet chemistry, biomaterials, material processes & characterizations, energy & semiconductor manufacturing, etc.
