Brad Harris

Brad Harris is an MSEE student whose research is in low power analog IC design, specifically using MEMs relays and low power circuits as wake up sensors. After graduation he will be pursuing a career in low power design. When Brad isn’t on campus he is hiking, learning new languages or enjoying comic books.

Taylor Vincent

Taylor Vincent received her Bachelor’s degree in Physics at UC Berkeley prior to attending graduate school at UC Davis. As an undergraduate researcher at the Berkeley Wireless Research Center (BWRC) she was able to help publish a paper titled “Joint impact of random variations and RTN on dynamic writeability in 28nm bulk and FDSOI SRAM” at the 2014 Solid State Device Research Conference. Also as an undergrad she interned for a fiber optics company in San Jose called GigOptix where she designed an E-Band Power Amplifier biasing board that has been in production since 2015. As a graduate student at UC Davis, Taylor shifted her focus to energy harvesting, and in particular vibrational energy harvesting. During her three summers before graduation she was able to intern three times for Intel. Two of those summers she was up in Portland working at Intel Labs in Wireless Communications Research, and was even able to get her name on two patents for Intel for her work. Her third internship took her to Boston to work at Intel’s Massachusetts Microprocessor Design Center (MMDC) where she worked on coverage test conversions on the next generation Intel Microprocessor. After completing her thesis, she accepted a job to work for Intel as a High Volume Manufacturing Testing Development Engineer. In her free time she enjoys running, biking, uking, and being a complete goofball.
