Engineer
Electrical Engineering & Computer Science
  • Shanghai

Dr. Ma’s background and experiences covers a broad range of areas including optics and optical telecommunication, optoelectronics, electrical system, semiconductor devices fabrication and physics, and polymer material for electronic application, as well as biosensor system. At Exponent, Dr. Ma has worked on laser system optimization, light emitting device failure analysis, PCB contamination and electrical failure on both manufacturing process and field return units, thin film/surface optical characterization, and flex cable failures analysis.

Dr. Ma’s Ph.D. dissertation focused on solution processed optoelectronic devices based on conductive polymer and colloidal quantum dots materials. Her works involves nanomaterial characterization using transmission electron microscope (TEM), scan electron microscope (SEM), atomic force microscope (AFM), photo-luminescent spectroscope, UV-Vis, and confocal Raman microscope; device fabrication with photolithography, sputtering tools, e-beam evaporator, and physical vapor deposition tools; device optical and electrical characterization including LED efficiency, spectrum analysis, LIV measurement, and electrical microprobing. She also has experience on optical and electromagnetic simulation, and design and characterization of optical and biosensor systems.
