Anna Fox (Fed)
Supervisory Electronics Engineer
Dr. Anna Fox is an internationally recognized contributor in the field of superconducting electronics and the design and fabrication of voltage standard circuits. Her body of research has enabled advances in voltage standard devices as well as reliable dissemination. Dr. Fox engineered the first reliably manufacturable 10V Josephson voltage standard and designed and fabricated the first usable Arbitrary Waveform Synthesizer (JAWS) devices. She is responsible for the fabrication process and fabrication of all the disseminatable voltage standard devices for the DC Voltage Reference (PJVS) and JAWS enabling the creation of the first ever NIST Standard Reference Instrument. Because of their metrological excellence and accessibility through the SRI program, Dr. Fox’s voltage standard devices are currently considered the realization of the SI electrical unit.
Prior to joining the Quantum Voltage project in 2013, Dr. Fox was a National Research Council Postdoctoral researcher in the NIST Optoelectronics Group from 2009 to 2010 where she worked fabricating superconducting transition-edge sensors for use at optical wavelengths. She continued her work in transition-edge sensor fabrication in the NIST Quantum Sensors Group where she fabricated arrays of TES bolometers for cosmic microwave background detection.
