Dr. Turner’s main area of expertise is reliability and failure of electronic materials and devices. At Exponent, Dr. Turner performs failure analysis of lithium ion battery packs, electrical appliances, portable electronic devices, DC power supplies, printed circuit boards, and power semiconductor devices. Dr. Turner has also performed investigations involving residential electrical wiring, low voltage switchgear, utility power distribution systems, static electricity hazards, fluorescent lighting, arc flash explosions, counterfeit integrated circuits, portable generators, vehicle electronics, solenoids, and building fires. During these investigations, Dr. Turner has made use of relevant standards and regulations from organizations including UL, IEEE, NFPA, OSHA, IEC, and ANSI. Dr. Turner performs on site inspections, custom tailored laboratory testing, background literature research, and has provided testimony as an expert in product liability matters.
Prior to joining Exponent, Dr. Turner studied electrical engineering with a focus in semiconductor device design. She has experience with several processes and equipment in the microelectronics and nanotechnology field, including 2-D device simulation, lithography, metal deposition via sputtering and evaporation systems, reactive ion etching, thermal oxidation, annealing, and probe station electrical characterization. Dr. Turner has 6 years of experience in the field of silicon carbide power electronic devices and has worked in a clean-room environment. She also has experience in related fields such as compound semiconductor characterization, fiber optics, scanning electron microscopy, circuit design and layout, VLSI, and computational algorithms.
Dr. Turner also has a variety of teaching experience, including graduate courses, undergraduate courses, a college test prep (GRE) course, and middle school math and science. Most notably Dr. Turner developed a five week course module on Power Electronic Devices that has since been integrated into graduate coursework in the Microelectronics and Semiconductors specialization at Purdue University.
