Dr. Hu’s area of expertise includes semiconductor physics and device characterization. Her doctoral dissertation investigated the growth and properties of a two-dimensional carbon material and its applications in microelectronics. She has extensive experience with design of experiments, device fabrication, surface characterization, and electrical and magnetotransport measurements.
Before joining Exponent, Dr. Hu was a senior scientist at Halliburton where she worked on developing gamma ray sensing instruments for oil and gas exploration and well integrity intervention using scintillation crystal and photomultiplier tube. She is also the author of more than 10 patent applications with the USPTO.
As a graduate research assistant at the Georgia Institute of Technology, Dr. Hu performed fundamental research in graphene physics and demonstrated the quantum phenomenon in graphene based electronics. She worked on understanding the growth mechanism and improved the growth process to achieve high quality graphene thin film obtained through thermal sublimation of silicon carbide in an induction furnace. She mastered laboratory skills in surface analysis (AFM, SEM, XPS, Raman, Ellipsometer, LEED), nanodevice fabrication (E-beam lithography, RIE, ICP, E-BEAM evaporation, carbon coater, ALD), and electrical and magnetotransport measurements (Lock-in amplifier, cryogenic measurements, Hall effect measurements, and resistivity measurements).
